Skrillex: 02 Academy, Glasgow

HERE THEY come — the tiger-print leggings, the vest tops, the T-shirts soon to be removed. It is 8.40pm. This 80-year-old art deco venue in Glasgow's Gorbals already has sweat dripping from the ceiling. The 24-year-old Californian playing tonight is not even on yet; a Bob Marley "best of" is getting the crowd going instead. This may seem strange if you've heard, rightly so, that the Californian plays brain-blistering electronic music. It won't if you've heard his two-day-old collaboration with the late reggae star's son, Damian, or realised that the music made by Sonny Moore — for he is Skrillex — is becoming the mainstream.
