Few L.A. bands have ever come close to reaching the heights of drug-, groupie- and hair spray-fuelled excesses of Poison. The late '80s saw the androgynous cock-rockers become one of the biggest bands in the world, going multi-platinum time after time again thanks to their cartoonish sleaze, mom-baiting antics and ridiculously catchy string of singles like "Nothin' but a Good Time," "Unskinny Bop" and the crowned king of the '80s power ballad "Every Rose Has Its Thorn." While the "dumber we do it, the sweeter it sounds" plan was a huge success in the studio, Poison was notorious for the live show: confetti, pyro, costumes and flashers galore. Say what you will about Bret Michaels, but you can't argue that the guy is a dedicated entertainer. Since reinventing himself as a reality TV star on "Celebrity Apprentice" and his VH1 dating show "Rock of Love," Michaels spent chunks of 2010 in the hospital, finding himself in critical condition after suffering a debilitating brain hemorrhage. Now he's rehabilitating on the road and celebrating Poison's 25th anniversary.
