Red Bull Music Academy have taken control of a stage at this weekend's Sonar Festival in Barcelona for the fourth year running, and this year's line-up is rather impressive, featuring the likes of Nina Kraviz, Salva, Nguzunguzu and Rashad & Spinn. Yesterday we published a widget that allows you to stream live, direct from the stage, at any point during the weekend. Now we've got a stream of Om Unit's set from last night, which you can listen to below. Om Unit's a beguiling shapeshifter of a producer - he's moved from producing tracks rooted in hip-hop to banging Detroit-styled electro, and more recently has been collaborating with Machinedrum as Dream Continuum, coiling together the twin percussive furies of jungle and footwork.
