In 2003, Adler formed the band Suki Jones, later renamed Adler's Appetite, with singer Jizzy Pearl, former Slash's Snakepit guitarist Keri Kelli, Faster Pussycat guitarist Brent Muscat, and former Ratt bassist Robbie Crane. With an ever-changing line-up due to members' previous commitments, the band toured the US and Europe throughout 2003 and 2004, playing mostly songs off Guns N' Roses' debut album "Appetite for Destruction", as well as material by Aerosmith, Led Zeppelin, and Queen. In September 2003, Adler's Appetite performed a show at the Key Club in Hollywood, where they were joined on stage by Adler's former Guns N' Roses bandmates Slash and Izzy Stradlin, for renditions of "Mr. Brownstone", "Paradise City", and "Knockin' on Heaven's Door".
