This is Hamdi's first appearance at Sónar... but certainly not his last. The UK artist is one of the most prolific dubstep producers around today. Having spent over a decade building his reputation on the UK circuit, in the last couple of years he’s gained international recognition, playing for crowds of over 30,000 people on the other side of the Atlantic. Dubstep fans: you’ve got a date on Friday at Sónar by Night.
