Primavera Sound (Barcelona, UK)

There ain't no party like a Primavera party, is not quite what S Club sang back in the day but it is true. Since its inception in 2001 the annual event has grown to be one of Europe's top festivals - and that's pretty much down to the calibre and variety of acts that it curates. Being based in such an intensely resplendent city such as Barcelona doesn't harm matters either.
