i need a song that builds up to a fast beat?

im looking for dubstep (or any song with no singing) that is slow in
the beginning, like the first 10 seconds or so. then builds up to a
fast beat.
for example, Requiem for a Dream (Andy's iLL Dub fix)

if you can find more than 1 song, then give me all of them. i'd like a
long selection.
