Yeah, So Solid were pioneers of Grime since they gave that Gangsta Rap image
to Garage but I would also say that some of the early Garage MCs were responsible as well; MC Creed, PSG, MC Viper, God's Gift (Pay As U Go- Roll Deep),
MC Kie, and MC Sharky. They've been around from 1994-2000ish when Pirate stations played Garage music.
My favorite Pirates are Vybe 99.5 and Ice Cold FM (Im amazed that they're online)
and favorite legal station is Radioweb.tv. Pressure Radio is ok for Old School Garage but theres is no Grime.
