Jack Revill, better known as Jackmaster, DJ and co-founder of Numbers, from Glasgow. You never know exactly what you’re going to hear with Jackmaster. The element of glorious surprise is crucial to his sets. From the lost Dance Mania gems he spends his time unearthing to forgotten Disco tracks to straight-up house and techno sets He has a rare knack for connecting seemingly disparate style.. Njoi! Thanks Jackmaster.
