New London producer Rationale first caught our attention with his sleek, emotive debut 'Fast Lane' earlier in the year - now he's back with another shimmering R&B jam in 'Re.Up'. It helps to pay attention to how artists tag their music on SoundCloud, Rationale decreed 'Fast Lane' "music to travel to", this latest cut is "music to f*** to". Indeed, sweet, soul-flecked male-female harmonies peal away - "Ooh I wanna be your lover" - over treacly guitar and skewed beats. Give him his dues, he's probably got that tag bang on. Pardon the pun. DC
