He just needs reined in a little. Honestly, all things considered, I don't think Buckethead's approach has really changed that much. He always fucked about a lot (interesting live, doesn't work so well in the studio), recorded way too much (either solo &/or with other people), and produced stuff that was magical (his best is awesome) down to mind numbingly frustrating crap (e.g. ambient/drone/noise releases). But, if he wants to go and make 30 ambient Halloween albums then who am I to stop him.
He's made his music pretty freely available too; there's just too much of it for most people. I look at people on this forum who listen to, say, Metallica or Megadeth (& would go & see them multiple times too) & who seem quite critical of whole swaths of their careers, whole albums, or who find everything they've produced has "filler" here & there --& honestly I don't see why Buckethead should be judged any differently i.e. take what's good & ignore what you don't like. That's difficult for an artist you really like, but there's no other approach with Buckethead.
