It's a bucket. Worn as a hat. Thus it is, technically speaking, a bucket hat. But really it's a KFC container, upended and plopped on the head of the singular guitar virtuoso known (but of course) as Buckethead. In 1999, the mask-wearing madman broke through with his album Monsters And Robots (a collaboration with Les Claypool of Primus) before going on to replace Slash as lead guitarist in Guns N' Roses from 2000 to 2004. Despite questions about his reliability, Buckethead was then primed to join Ozzy Osbourne's band, until Ozzy insisted he remove his bucket. Buckethead refused. Which is awesome.
