Renegade Hardware - Quantum Mechanics (1998)
cd one is a shitload of BUTTER singles. cd two is a mix, and an excellent one at that mixed by future members of what would be to become bad company. also features tracks by future members of the virus crew and dillinja. all early stuff by them, not the shitty shit shit they put out nowadays.
theres a double disc release with 1 mix on each disc by dj dara called "renegade continuum 2". do NOT, i repeat, do NOT get vol 1. it sucks shit.
this cd got me into the dnb scene OFFICIALLY. i still listen to it regularly, even after 7 years (at least once a month in it's entirety). nothing in the world touches this sound. screw everything. the 2ng gen tech step movement was the BEST. fuck everything else.
