Under today’s window on FACT’s 2012 Advent Calender is Dobie.

A fixture in the UK underground for a very long time indeed, Dobie has produced for Soul II Soul, London Posse and more, while artists as lofty as Tricky and Bjork have demanded his work as a remixer. In February, he’ll release a new album on Big Dada, We Will Not Harm You, and it’s the label that you can thank for this track: the whirring, demented ‘Twitter Riddim’.
