Top-dog producer Sir Spyro has added Plan B to his ever-growing roster of beats, as he throws everything toward a new remix of Heartbeat, the lead single from Plan B’s upcoming project Heaven Before All Hell Breaks Loose. From downtempo grime to jazz undertones, this one’s massively special, and huge props to Spyro for adding an extra element of depth onto the already-excellent joint.

Catch a listen in full below; if this is the first you’ve heard of Sir Spyro, then we’d highly recommend you bump his weekly Friday night show on 1Xtra.
