RATT may have broken up in the mid-90s, but like a couple that can't call it quits, they get back together every few years. Between solo projects, Pearcy (pictured in Las Vegas on Aug. 5, 2010) reunited with his old band to record new albums in 1997, 1999 and 2010 -- even after they replaced him with another singer in the '00s. He revisited his biggest hit, RATT's "Round and Round," when he did guest vocals on a 2008 cover by all-girl rock band The Donnas. In 2011, Pearcy announced via Twitter that another RATT reunion was in the works. The singer released a memoir in May called Sex, Drugs, Ratt & Roll: My Life In Rock.
