What about posting something about other great artists in music which you like, apart from Billy and the Pumpkins? Maybe with a pic and/or a short description why you like them?

So, this is Steven Wilson, a London progressive-rock songwriter.
He's got several projects, but his soul definitly lives in Porcupine Tree! I saw them live in Fall'07 and it was so intense, that this show made him the only musician who can mess up with Billy Corgan (in my opinion, of course).

And that's the the 10 minutes overload "Russia on ice" which is my personal favorite track. You won't believe, but the final is hardcore! (don't pay that much attention at the video, it's fanmade)
