It's pronounced "subtract", which is the name this south London producer goes by, preferring anonymity lest anything detract from his music. If only it were more distinctive. His debut album is a bang-up-to-date summary of where British electronic music is at post-dubstep and the xx winning the Mercury prize, which is to say it's entered its coffee-table phase. So while there's a roster of guest vocalists and an emphasis on tasteful songwriting, it's all too smooth, lacking the reckless thrill of the audacious remixes of tracks by Radiohead and Goldie with which he first attracted attention.
