Frost (Satyricon/1349) impresses me simply because he hits the double kick so fast without the aid of triggers.
Yes, triggers allow a drummer to produce a full, loud tone without hitting the pedal hard, since it's just a synthesized drum sound that is being "triggered" (thus the name). Listen to Hellhammer's drumming on the past few Mayhem albums and on "In Sorte Diaboli" by Dimmu and you'll see what I mean. It's just not possible for a human being to play that fast without triggering the kicks.
Not that it's the fastest but Decapitated Spheres of Madness has one of coolest double bass beats ever.
Fuck people who are all against pedals and shit.
