Massive Attack

After disappointing heaps of fans with their cancellation at last summer's Mad Cool festival, the British trio have accounts to settle with the Madrid public. This time around they have no reason not to take the stage and commemorate the 20th anniversary of 'Mezzanine', one of the biggest trip-hop albums ever. Expect special guests like Elizabeth Fraser, the iconic Cocteau Twins singer, who lent her voice to 'Teardrop'.
