Rap: Eminem, Jay-z, DMX, even Biggie Smalls or Tupac for old school rap fans?
Electro: Noisestorm, KOAN Sound (For the more underground of us), Rameses B, Electroconductor, Adam Sennit?
None of the electro artists make dubstep which is good, and they're pretty underground. If you're way old school, like, way back in the day, does anyone listen to Alex Reese? He was a really good DnB artist.
