Scuzzy garage/glam guitar and drums - check. 80s dress code - check. Tours with major rock artists - check. Friends in other bands including The Horrors and Haim - check. Born out of a love of crocheting - chec…wait, what?

The 405, meet Deap Vally - a delicious paradox of macho swagger borrowed from hair bands of the JD-glugging foot-on-monitors-during-a-solo variety, matched by snarling feminist lyrics and upfront attitude - this is an outfit all about flipping rock and roll on its grizzly tattooed forehead.

Lindsey Troy and Julie Edwards look and sound like the real deal. With a body-slamming arsenal of three minute scorchers featuring some of the fiercest stripped down blues rock since White Blood Cells, and a flight case of leather jackets, leopard skin leggings, the shortest shorts and cowboy boots to complete the Stevie Nicks meets Donita Sparks 'classy and ass-y' style, who's to argue about Deap Vally's authenticity? And so what if they met at a crocheting class - the rock and roll of the textiles world?

The band - lauded by media ranging from Kerrang! to The Guardian to Company magazine - hail from Los Angeles, home to the I-405 interstate - America's busiest and most congested freeway.

"Yeah!" exclaims Lindsey, down the line from Germany. "There was this time a few years ago when the 405 got shut down for a day, for construction. Fuck, what did they call it? Um… shit… there was some name for it that was like, the end of the world. What is it? Oh I have to text my friend to find out. Though I never really took that freeway - it's more on the west side of LA whereas I've always lived on the east side." The answer by the way, road fans, is Carmageddon.

Autobahn/motorway/freeway small talk and tenuous connections between Deap Vally and The 405 aside, what's the latest from Camp DV?

"I'm in Berlin, and I'm eating candy." The singer says. "I'm starving and I've been trying to get my hands on some food and I'm getting really desperate - it's like a Kit Kat and Twix - I don't even like candy. I got a little bit…I'm hungover." she confesses. "I haven't really been drinking recently because it's bad for my voice - but I've had a few days off and one of my best friends who I'm staying with in Berlin had a dinner party last night."

Lindsey and Julie are at the start of a thirty-date worldwide tour that began with a set at Glastonbury on Sunday and takes in shows at festivals across Europe, Australia, the US, Canada, the UK again (Leeds and Reading), then South America. So the odd day to enjoy a Karlsberg or two may, we suppose, be justified.

"We're playing loads of festivals! Which is so much fun, so awesome. We were really blessed this year by the festival god - we're playing every amazing festival. So blessed to play fucking Coachella, Bonnaroo, Glastonbury, Reading and Leeds. Touring is fun but it can also be isolating, so it's fun to tour with bands who are cool people that you like, so you can make great friends and share the experience."

Though the duo have only been touring together since last summer following the release of debut single 'Gonna Make My Own Money', they've already connected with a ton of other artists playing the same circuits.

"We kept seeing Of Monsters And Men everywhere, and Gabriel Bruce, The Horrors, The Vaccines. Then this year we keep running into Haim, which is awesome because they're good friends of ours, Father John Misty - we're huge fans, Peace - they're really sweet, and Kasabian. They had really kind things to say about our music, really complimentary."

"We met Gogol Bordello the other day at a festival. It's just funny. I had met Eugene (Hutz, frontman) eight years ago, when I was a waitress in Hollywood at a diner, the late night graveyard shift at Mel's Drive In. It was like a really fucking crazy job to have - a real slice of life experience. We were talking and ended up hanging out - I didn't know who his band were at the time, that was my first introduction to them - and jamming with the fiddle player etc. Their music is great, so unpretentious."

Where months of touring across four different continents might kill off a lesser collection of musicians, the singer/guitarist is resolute and confident about dealing with life on the road.

"It actually feels a lot easier than it did six months ago. We've established ground rules. We'll do three show days in a row then we'll have a day off. There have been times where we've done ten days straight playing shows and I started to lose my voice. So now we have boundaries that we set. We've been living on the road for the past year so we're getting better at it. Whenever possible we bring friends along for a nice light energy to have around us. We have a really amazing crew now too - we've found our people and have a pretty zen tour."

Okay, so 'zen tours' might mean that dwarves carrying bowls of cocaine around, TVs exiting hotel windows with force or Cadillacs driven into swimming pools are off the menu, but that's the business these days (mostly) and anyway, the searing sounds on record and live more than help to make up the band's rock and roll credentials.

Sistrionix, their debut album which was released earlier this week, is a killer record, containing verve, passion and explosive musical dynamics. It's an album that trades not on showy guitarwork or overwrought arrangements, but on sheer volume, drive and back-to-basics gritty rock magic.

As The 405's Larry Day put it in his glowing review of the album, "There's confidence by the bucketload - Deap Vally aren't ashamed or shy about stomping right up to your face and hocking a phlegmmy wad of spit between your eyes."

Such delightful plaudits must be fantastically reassuring for a band that haven't really been around that long, however Lindsey confesses to not checking out most write-ups, preferring to draw her own conclusions from audience responses at live shows.

"I honestly try not to read reviews. It's like, if someone was talking about you - or if you could hear every entire conversation people had about you, would you really want to hear them?! I've read a handful of reviews, most have been fantastic."

On Deap Vally's speedy rise to fame, even by 2013 standards, Lindsey is quick to recognise their success story: "It is incredible that this is happening, that we have a platform and a voice in the world and that people are listening to our music and taking an interest in what we say. That's really, really incredible. What's funny is that it feels really normal. I think Julie and I feel we were just made to do this!"

"A few years ago I felt like my life was going nowhere fast, I was working as a background actor and just not making music." She goes on to say. "I felt miserable and I felt insane and that my life was not where it should be. And I had a moment, an epiphany where I was like; I'm going to make music. I'd been doing singer-songwriter stuff for years and I'd always wanted to be in a rock and roll band but I'd just never met the right people, so I just started making music on my computer. I became focused and determined, I'm going to have a career doing what I love - shortly thereafter I met Julie."

As the guitarist who delivers monumental riffs and heavyweight power chords on all of their tracks, Lindsey has a specific set-up to deliver the 'Deap Vally' sound, along with Julie on drums (a minimal Gretsch kit).

"I'm a little bit coy about the pedals I use." She says. "My guitar is a 70s (Fender) Mustang. I got it from my Dad, who bought it from a friend of his who was living in his van and needed money. When Julie and I decided we were going to start a rock n roll band I asked my Dad for the guitar…and I'm not giving it back! I love that guitar so much."

"We played some shows with the Yeah Yeah Yeahs and Nick Zinner - who is one of my guitar heroes - was snooping around my pedal board. But he can do that as much as he wants! He was like 'I don't know how you do it; I used to play a Mustang and it always sounds so thin.' They traditionally have that twangy sound so I think it's a matter of the pedals I run it through, the combination of amps I use and also because the guitar is vintage - it does have a different sound."

And on the subject of heroes, like jazz, folk and electronica, rock constantly operates on a cyclical basis, with artists and bands reinventing themselves whilst still acknowledging and drawing on music from the past. Who does Lindsey cite as her go-to inspirations?

"I have a handful of them. My heroes are everything to me, they are the reason I do what I do. Karen O is incredible. Fever To Tell is my all-time favourite album! Playing shows with the Yeah Yeah Yeahs was a dream come true - they were all such lovely people. Karen dedicated Maps to us every night. It was just great nerding out about music with Nick! Jack White would be another one. We have so much respect for him. Also Joan Jett, Kurt Cobain, Courtney Love, Jimi Hendrix and Jimmy Page."

One of the best moments of our chat came when Lindsey offered up a genuine thought about Deap Vally's experience to date.

"I only hope that everyone can have such an experience in their life as we're having, whatever they really want to do. Everyone has a true calling inside of them and if they can find the confidence and courage to live their life how they want, whether or not their parents approve or whether it's not glamorous or it's too glamorous or whatever the hell it is - I think the world would be a happier place."

And there you have it. A rock and roll band with a conscience, driven by the love of music (and crocheting), delivering a killer sound. No doubt a record label exec's wet dream, but an awesome force regardless. Good luck to Deap Vally, though it's highly unlikely they'll need it. Rock on.
