This weeks riddim of the week (well ok since I missed last week, riddim of the fortnight) from Massive B contains one of the most classic basslines in history...

Massive B - 210 Computa Riddim

Don't know where that bassline came from originally but it's been reused approximatley a squillion times, always to devastating effect... here's a couple of examples that spring to mind:

heavy heavy roots: kenny knots / bush chemists - good sensimiella

classic classic rave: SL2 - Way in my Brain
