Band didn't implode. Billy has always been the driving force of the pumpkins, and as a result the other members maybe felt they wanted more input into the music.I'm a pretty big pumpkins fan; mostly the stuff from Gish, Mellon collie, and Siamese dream. Some pretty solid stuff on those albums, with Siamese dream being Billy's brain child. I'd love to own one of his strats, but they'd probably fetch a pretty penny since those were his career defining guitars.
After Melon Collie and the infinite sadness, Billy got weird though. The guy is seriously not level and is the reason the band imploded. Last I heard he was running a wrestling franchise.
Rod Stewart used that on Carmine Appice when asked why Appice left the band: "He was getting sick - to my stomach" (ouch!)One of my favorite quotes regarding him was from Sharon Osbourne when she briefly managed them.
“It was with great pride and enthusiasm that I took on management of the Pumpkins back in October, but unfortunately I must resign due to medical reasons – Billy Corgan was making me sick!”
