The Drive-By Truckers are an alternative country/Southern rock band based in Athens, Georgia, though two of five current members (Patterson Hood and Mike Cooley) are originally from The Shoals region of northern Alabama, and the band strongly identifies with Alabama. The band currently consists of Mike Cooley (lead vocals, guitar, banjo), Patterson Hood (lead vocals, guitar), Brad Morgan (drums), Jay Gonzalez (keys, guitar, accordion, backing vocals), and Matt Patton (bass guitar, backing vocals). Like many alternative country acts, the Drive-By Truckers record in analog (using 2 inch, 16-track open-reel tape recorders). The band's constant touring has developed its dedicated following.
With Jason Isbell
After signing a new deal with Austin-based record label New West, Drive-By Truckers set about recording the follow-up to Southern Rock Opera. The result was 2003's Decoration Day, which like its predecessor, received much critical praise. It was another concept album, containing characters who are faced with hard decisions about marriage, incest, break-ups, revenge, murder, and suicide. The album featured an eclectic mix of the band's newer rootsy, hard-rocking sound with some of their older alt-country sound. Former member John Neff returned as a guest to play pedal steel on about half the album, although he did not tour with the band for the album.  After years of producing and playing with Drive-By Truckers, bassist Earl Hicks left the band on December 22, 2003. Hicks was immediately replaced by studio bassist Shonna Tucker, then-wife of guitarist Jason Isbell. Tucker had previously guested on Decoration Day, playing upright bass on the Cooley-penned track, "Sounds Better in the Song."  In 2004, Drive-By Truckers released yet another concept album entitled The Dirty South, which further explored the mythology of the South, with songs focusing on Sam Phillips and Sun Records, John Henry, and a three-song suite about Sheriff Buford Pusser. With Cooley and Isbell each contributing 4 songs on the 14-song set, it was the band's first album for which Hood did not write the majority of songs.  After touring throughout 2004 and 2005, Drive-By Truckers found their way to the Fidelitorium Recording Studio in Forsyth County, North Carolina, during late 2005. These recording sessions, once again produced by David Barbe, resulted in the band's seventh LP, A Blessing and a Curse. Released on April 18, 2006, A Blessing and a Curse showcased Drive-By Truckers' ability to branch out into new territory, and can be seen as the band's attempt at shaking labeling by critics, detractors, fans, and followers, particularly the Southern rock label that has haunted the band since Southern Rock Opera. The album sounds less like Lynyrd Skynyrd, and more closely resembles the bare-bones British rock of the early 1970s such as The Rolling Stones and Faces. Tom Petty, Blue Oyster Cult, and Neil Young's influence on the band's sound is more prominent on this album, as well.  On September 1, 2009, Drive-By Truckers released a collection of B-sides and rarities entitled The Fine Print: A Collection of Oddities and Rarities which were recorded during the Decoration Day and Dirty South sessions. Though released after he left the band, the album includes two tracks written by Jason Isbell.
