In the interest of spontaneity, there is no schedule for performances; but if you see Buckethead setting up corpses like an audience, there's a good chance of live music. —Bucketheadland Vol. II, "Today's Schedule/The Corpse Plower"
But then you see some guy like Buckethead? Buckethead is probably twice as good a guitar player as me and Slash combined, and can stand having fried chicken rubbed up against his face all night for a couple of hours. —Dave Mustaine
Achievements in Ignorance: See below. As Shawn Lane once mentioned, Buckethead managed (or at least came very close) to play "Kaiser Nancarrow", because he didn't know Lane composed that song in a way that it was unplayable in real time.
Affectionate Nickname: Most of his friends and even some fans call him "Big B". His mother used to call him "Boo" for liking scary things.
Ambiguous Disorder: Some have noticed that some of his mannerisms are reminiscent of autism or Asperger's Syndrome, though nobody knows for sure because nobody knows how much of it is in character. Or if he's just extremely weird.
A lot of people assume Buckethead's persona is just a stage gimmick, and that he is a normal person offstage. They are very wrong. Buckethead's persona is basically just a way he's found to allow himself to cope with his crippling fear of people. Offstage, however, he is pretty much just as weird in his private life. One anecdote going around was that when he was playing with Guns 'n Roses, while they were recording music in the studio, someone jokingly suggested that they build a chicken coop in the studio for Buckethead to live in. Buckethead loved the idea, and proceeded to do just that.
Dark Is Not Evil: His appearance and eccentric behavior usually mark him as creepy and odd to most people. His friends and those who work with him, however, often state that he's a really nice guy.
Doing It for the Art: So far, none of his albums have been made with catering to the masses or making huge sales in mind. He seems to only compose whatever he likes and even created Death Cube K as a side project, just so he could publish several albums without Sony's Executive Meddling.
While, interestingly enough, Red Hot Chili Peppers thought he was "sweet and normal", which was their reason for not accepting him in the band. And Axl Rose had no qualms with getting him in Guns N' Roses, despite the obvious clash of the musician's gimmicks and the band's style.
The Faceless: Although there is an old video and a picture that (not very clearly) show his face when he was young, there's no way to see him without a mask, unless you work with the guy.
Genre Roulette: The man does everything. He tends to like separate genres by album, but sometimes he'll switch it up during the course of one, or even MID-SONG.
Iconic Item: The white mask and plastic bucket, naturally. His custom made white Gibson guitar with a red killswitch may also count, as he seems to be using it almost exclusively.
Indecipherable Lyrics: In several of the songs that have lyrics. Like in "Frozen Brains Tell No Tales" due to the distortion of most of them.
Kayfabe Music: Buckethead is a persona Carroll himself thought up.
Man Child: Could be seen as such. He never talks while being filmed or infront of fans without his puppet, Herbie. Also, he often plays with or trades toys during live performances and is a big fan of the Disney Theme Parks.
Miniscule Rocking: Many songs, but probably the most prominent examples are "Pickwick's Lost Chapter","Electric Bell Blanket" and "Big Sur Moon".
Mistaken Identity: For a time people would find pictures on the Internet of a tall guitarist with long hair, standing next to Shawn Lane. Immediately someone rushed to the conclusion that it's Buckethead unmasked, because he knew Shawn Lane personally. Turns out it was the French guitarist Stephane "Fanalo" Alaux, who just happens to be tall like Buckethead and had also met Shawn Lane and even Paul Gilbert at one point. Apparently Fanalo got so many e-mails of people asking him if he's Buckethead (despite the fact that Buckethead's American, a few years older, etc.) that he now explicitly states on his myspace and facebook that he isn't. Amusingly enough, Fanalo wrote on his official site that he admits to being guitarist Bumblefoot (which he isn't either). He also posted a picture of himself wearing a popcorn bucket on his head and covering his face, as a jest to the many who called him Buckethead.
What's more, many people are still convinced either that those pictures of Fanalo are Buckethead's or that Fanalo is Buckethead and is trying to hide it. All that despite the fact Fanalo has a different playing style and lives in France and performs exclusively there, while Buckethead lives and performs in the US at the same time.
Murder Ballad: "Unemployment Blues" is about a gutter at a slaughterhouse getting fired and subsequently killing all his former coworkers in the showers. It's actually narrated, rather than sung, with the narrator being the killer.
Nightmare Fetishist: Practically embodies this trope. He adores horror, has a video filmed in a cemetery, owns rubber body parts and scary masks, one of his hobbies is taxidermy, etc. And in both recorded non-serious interviews (20 years apart) he still talks about visiting slaughterhouses and covering himself in blood.
No Social Skills: Buckethead acts like this when filmed and interviewed. Whether the man himself behaves in any way similar in his daily life, or the whole thing is just playing the character, is not known.
Obfuscating Insanity: No one denies that he's very eccentric, but he's not as crazy as his stage persona.
One of Us: He once mentioned in a written interview that he's an avid video gamer, grew up with a room full of comic books and is also interested in Star Wars (one of the knobs on his guitar used to be a storm trooper head). And, of course, one of his inspirations - Giant Robo.
Screw This, I'm Outta Here: He quit Guns N' Roses rather abruptly, with his manager claiming Bucket's main reason was he got fed up with the band not making any progress on a single album for 4 years. In turn, Axl Rose blamed Buckethead's eccentric behavior as the cause for problems with the band's schedule.
Shout Out: Almost all of his music contains references to people he admires and things he likes.
Shrinking Violet: Admits he's very shy and using the Buckethead persona makes it easier for him to express himself.
Word Salad Title: Oh, plenty. Some of the more notable are "Bloody Rainbow Spiraling Sherbert Scoop", "Carpal Tunnel Tomb Torker", "Gory Head Stump 2006 The Pageant of the Slunks", "The Hills Have Headcheese", "Heaven of Black Tar Pitch" and others.
