To call Billy Corgan a whining twat on a Morrissey board is incredibly hilarious to me.
I think SP were fantastic -- and to even lump them in with flannel-clad grunge is nonsense (have you ever seen him wear a flannel shirt?). Their music was far more imaginative than Pearl Jam's or Alice and Chains, and I'm not sure why those bands are so holy and SP so hated. Pearl Jam is flat out boring to me and the Foo Fighters seriously haven't been interesting in at least 15 years, making the same album again and again. Who are we kidding?
And seriously, maybe he was playing the game, but Gish and Siamese Dream were far too personal and too good (the latter widely considered one of the best of the 90s) to be merely cheap shots for indie cred, which they never had anyway. (f*** indie cred anyway.)
And since when do we give a shit who slags which other bands? Need I remind anyone this is a Moz page? Can you tell me how often he says nice and pleasant things about his contemporaries? He doesn't ever say bad things about other artists, does he? I don't think Billy even did much more than give his honest opinion... he still gave those bands some credit. Hardly bashing, anymore than if you said "I don't like that band." But no one seems to hear that part. Funny.
Matt Walker also toured with the Pumpkins for years and recorded on some of their albums. He was originally in Filter, from Chicago... so yeah, they're friends.
