Two of grime’s grittiest team up over The HeavyTrackerz.

Family Tree’s Merky Ace and Cadell have formed an interesting alliance lately, and you can see how naturally they bounce off each other in this session. Both have been putting in work lately, too: Merky’s ‘Polyphonic Ringtone’ single was one of the best grime tracks from the end of last year, while Cadell teamed up with Zomby on ‘3 Is The New 6’ – he also jumped on stage with him at last year’s Clock Strikes 13 and XL party.

Instrumental heads, we’ve uploaded the beat below:
