Masters of the 130 bass sound, Bristol-based duo Tommy and Jammo peddle an instantly distinctive dark groove that resonates with all corners. Launching on Mindstep Records in 2011, they've gone on to demonstrate their skills on labels such as Ram, 877 and, most recently, Black Butter who've signed them exclusively.

Talk about high expectations. When London drum’n'bass duo, Chase & Status aka Saul Milton (Chase) and Will Kennard (Status) first laid down the tracks that would make up their third studio album, they were faced with a weighty dilemma: how to follow the sizeable footprint left by 2011’s multi platinum selling No More Idols, not to mention their hefty rep as festival headliners? The answer was found with Brand New Machine, an album that brims with surging, dancefloor anthems, dusty trip hop grooves as championed by the likes of Massive Attack and Portishead, and a collection of jungle and garage breakbeats that increase with substance over repeated plays. Meanwhile, brooding ragga harmonies and hip hop samples deliver an updated take on No More Idols’ anthemic, catch-all appeal. The overall vibe? An instantly memorable collection of swaggering cuts tuned to a club setting, hyped summer festivals and arenas alike.

Award-winning duo from the UK and Norway, Calyx & TeeBee both carved their own distinct sounds as solo artists before joining forces in 2004. Two albums, many singles and one exclusive deal with Ram Records late and they're regarded as one of the best partnerships in drum & bass. Their early work inspired Noisia to produce and their six-deck-two-mixer shows are the stuff of scene legend. Serious D&B soldiers.
