Skream just released a "Freeism" pack, a bunch of awesome classic garage/dubstep/UK bass tunes. Some great "real" dubstep, or at least dubstep at its roots.
Ok now time for 500 posts on how dubstep sucks. But take a listen, its certainly not the kind of dubstep a lot of you are familiar with. But do it on good headphones or decent speakers, not just your laptop.
