I'm so glad this hasn't turned into some ridiculous "shred is tasteless" topic. Buckethead is absolutely fantastic, and I think that his music, great deal of which is amazing music is overshadowed by people who want to label him as some kinda tasteless showoff.
Go the bucket!!!
Oh by the way, 2:40 into The Treeman, from the Cuckoo Clocks of Hell is the greatest riff ever.
