This week in break-ups... Smashing Pumpkins

* Jimmy Chamberlin, the one non-Corgan original member of the Smashing Pumpkins, has left the band. This is the first time he's done so of his own accord (he was kicked out due to a heroin addiction in '96, but came back to the fold eventually). Corgan still plans to record and tour as the Smashing Pumpkins.

* Nothing concrete, but John Frusciante just released a solo album, and Chad Smith is now drumming for Chickenfoot, the new supergroup featuring Joe Satriani, Sammy Hagar, and Michael Anthony. And I haven't heard much from Flea or Anthony Kiedis in awhile. Are the Chili Peppers still together?

* Don't expect to see more Rage Against the Machine dates this summer, as Tom Morello has a new band called Street Sweeper that'll be opening up for Nine Inch Nails and Jane's Addiction.
