This video has some cool, odd percussion.  Beatbox, Spoons, a metal bowl etc.  These guys have a ton of great videos & are really talented to boot.

High Notes ?

"Singing in the Rain" (from A Clockwork Orange) 

Everything on the album - "Lark's Tongues in A s pic" by King Crimson, with percussionist Jamie Muir.
 
I missed a KC concert during this period. A friend of mine said Muir was thrashing a metal sheet with a chain and miss judged it and himself in the face with the chain, drawing a considerable amount of blood.
