www.waxfm.com a London pirate station.
Grime, is a style of Garage, the same way, Grimey Drum and Bass is the harder stuff of dnb, Grime on its own, is refered to as the music style from Garage, its a 4x4 repeated beat, oftern without any lyrics, just pure beats/bass line, its intended for MCS to mc, spit over the top of.
Its the dirtier style of garage, darker, more underground style.
Basicly Vocal Garage is for the girls, Grime for the boys, thats the comparason. Its the heavyier style. Same with Grimey, Drum and Bass or Grime, refering to heavy, drum and bass. the word grime = dirty. its the dirty style.
Up front fm, rinse, flava, my station wax fm on a tuesday for examples of grime at its best.
When I play grime, I play so the mcs have a tune to mc over, and can flow without getting twisted up with vocals on the tunes.
PS "fix up look sharp" as in Dizzee rascal, is not grime, his style of music is COMMERICAL GARAGE, as with Lady Soverion, ms dynmite.
Grime is also known as, Eski, dublow, sublow. underground garage.
