Never saw/heard him slapping before...

[Alvaro Martín Gómez A.]

...and that's what makes this video so cool to me (not to mention the whole band's performance, of course):

I saw him twiddle around with slapping in some video on Youtube but it sounded nowhere as good as this!
I rally gotta check out more songs by Niacin, I like this a lot more than Billy's rock shredding.

Very cool stuff, but the key sound is still hideous. That said, you gotta love Billy. I've seen him slapping on both the occasions I saw him live, but never to this extent.

Billy's an awesome player, but I can't stand his tone!

I find it nearly unlistenable.
