Yer blastbeat is when ya hit yer bassdrum and then yer snare and/or cymbal (cowbells and highhats sound good =) in an even, alternating rhythm, (bass - snare - bass - snare - ad infinatum) and ya do that from moderate to fast speeds. Black metal and death metal use it most, and so does thrash to a lesser extent.
