“Modular business.”

Mumdance, aka Jack Adams, and one of our favourite new grime kids on the block, AJ Tracey, have joined forces for an RBMA session that blends Adams’ modular synth improvisations with a grime freestyle from the west London MC (who also delivered this killer FACT freestyle last year).

The result is an impressive meeting of minds, bolstered by woozy visuals from artist Henry Driver. Watch the final session below, along with a short explanatory video from Mumdance.

Mumdance heads up a modular synth workshop in Glasgow on October 16, with Russell Haswell, Aleks Jurczyk and synth designers ALM Busy Circuits also appearing at the event.
