Okay, a lot of us know that Tech would like to work with Slipknot and Serj formerly of SOAD (System Of A Down) but how about...
Bad Brains (H.R. speed chattering is like a precursor to speed rap)
Living Colour (did a track with Run D.M.C. and it was pretty good)
Red Hot Chili Peppers (Worked with LL Cool J)
Any other suggestions?
