So, last year I went to Roskilde and chose to see Tame Impala instead of some really good Danish band that you've probably never heard of. Anyway, just a week before seeing Tame Impala, I had read on these fora that Tame Impala were shit live at Glastonbury - I still chose to see them and yes, they were shite. So, give me some help. Maybe I'll take your advice more seriously this year.

Things (I think) I'm definitely seeing:

Cure
Apparatjik
Of the Wand and the Moon
Lee Ranaldo
Jack White
Mikal Cronin
Oneohtrix
Julia Holter
Alison Krauss
Roots
M83
Bon Iver
Liturgy
Dead Skeletons
Korallreven
Santigold
Björk

Any of those really bad live? What am I missing?

Are Shins any good live? Worth seeing or just dead boring? Are Perfume Genius worth seeing over Janelle Monae? What more? What else?
