Every year seems to have one or two artists nobody was thinking of on the lineup, one notably absent from predictions and fake posters. You know, the ones where we go, "Holy shit!" when we see the name since nobody saw it coming. For example (IMO)...
2009: Leonard Cohen, Throbbing Gristle, Beirut
2007: Happy Mondays?
2006: Daft Punk, Massive Attack
Who will be the surprise artist(s) of 2011?
