Day one UK rap fans will no doubt be all over this already, but for everyone else, here's Calley (fka Calibar), Shef and Young Spray teaming up for speaker-busting new single "No Days Off".

A huge, swaggering production from TRAP1ST forms the track's backbone while Calley and Young Spray stride over the beat with their contrasting flows and nimble wordplay. Which just leaves Shef to add a melodic, trappy hook you'll be quoting for days.

Regardless of your personal tastes, "No Days Off" is a welcome reminder of how many different strains UK rap has to offer right now.
