Buckethead consists of Brian Carroll.
Buckethead is a guitarist and composer who has recorded several solo albums, as well as collaborative albums with Bill Laswell, Bootsy Collins, and System of a Down's Serj Tankian, whose primary concern is virtuosity and blinding fretwork speed. His numerous limited-release albums cover and blend many different musical genres.
Buckethead was a member of Guns N' Roses from 2000 to 2004. He quit the band due to personal differences.
Buckethead has also recorded under the name Death Cube K (an anagram of "Buckethead" he created to circumvent legal complications with the Sony record label he was dealing with at the time). William Gibson later borrowed "Death Cube K" as the name of a bar in Idoru; quoting Gibson in an interview for Addicted To Noise:
"Death Cube K is actually the title of an album. I'm sorry I can't remember the name of the group but Bill Laswell who I don't really know but out of the kindness of his heart occasionally sends me big hunks of his output, groups that come out on his label. And Death Cube K was the title of some vicious ambient group that he had produced. And when I saw it, I thought: a Franz Kafka theme bar in Tokyo."
In an interview with Revolver, Ozzy Osbourne stated that he had offered to have Buckethead play for him at Ozzfest. Ozzy quickly changed his mind after meeting with him when Buckethead refused to go on stage without a disguise.
"I tried out that Buckethead guy. I met with him and asked him to work with me but only if he got rid of the fucking bucket. So I came back a bit later and he's wearing this green fucking Martian's-hat thing. I said, 'Look, just be yourself!' He told me his name was Brian, so I said that's what I'd call him. He says, 'No one calls me Brian except my mother.' So I said, 'Pretend I'm your mum then!' I haven't even got out of the room and I'm already playing fucking mind games with the guy. What happens if one day he's gone and there's a note saying, 'I've been beamed up?' Don't get me wrong, he's a great player. He plays like a motherfucker!" - Ozzy Osbourne
