One of the best old skool dubstep records ever made. Also one of the most expensive. If you find one on vinyl you can make a very pretty penny selling to collectors. I recommend good headphones or a good sound system for this, the best part is the deep wobbly bassline.
Yes, this is what dubstep used to sound like. I don't want to go all genre nerd and say modern stuff (post-Skrillex) isn't dubstep, but it sounds pretty different. If you said "dubstep" in a record store from 2005 - about 2009 then this is the kind of music they'd point you to (if they had it)
