Watched a few sets this weekend on iPlayer. Highlights were:
Young Fathers - really good performance, words can't really describe.
Viagra Boys - Was hoping to see them at a festival earlier this year, but clashed with another band. Pure swagger, and really got the crowd going. That mosh pit looked awesome.
Nova Twins - Totally kicked arse. Saw them last year at a festival for a song or two, and wished I'd stayed.
Sparks were ok as well.
If I'd been there, I probably wouldn't have gone near the Pyramid Stage (Royal Blood being a possible exception). GnRs well past their sell by date.
