Ebola is one of the Dubstep greats in my opinion, he put out loads of great free music to sink your teeth into; if you can still find out (can't seem to at the moment). Categorized as"Avant Garde Dubstep" its plain to see he was pushing 140-ish bass music to its limits of obscurity while still being danceable.
Much like Ebola, Milanese is one of the Dubstep/bass music greats, with his album 'extend' he made his mark on the classic era of 'pushing the boundaries' when Dubstep, Breakstep and IDM combined forces to create haunted landscapes, twisted bass lines and some of the most groovy but techy drums you'll find in modern dance music.
My favourite grime instrumental of all time; this track creates a dark, bleak landscape while being smothered in harmonically rich bass tones, minimal spacey drums complete this as one of the best 8 bar loop tracks to bless my ears; theres some brilliant vocal versions of it; Keedo's is my favourite but alas, its not on youtube/soundcloud/anything legit.
One of my favourite dubstep releases's still to this day, Jack Sparrow lays down a barrel of space, pace and bass with this skippy dance floor swashbuckler.
