Mura Masa is BBC1/ Annie Mac's : "Ones To Watch 2015"! Until December last year music was simply a hobby for Alex Crossan, aka Mura Masa. He may have had 7 million plays and 30,000 followers on Soundcloud but the 18 year old Channel Islander had never played his music live, DJ'd or even been to a gig himself. He had just started an English degree at Sussex University and was happy playing guitar and bass in function bands.
