Got back from Bloodstock 2010 a few hours ago (for those that don't know, it is a Heavy Metal festival in England). It was AMAZIIIING! So many bands I liked this year! I went to see:
Ross the Boss
Ensiferum
Sonata Arctica
Powerwolf
Hospital of Death (not reeeally my thing, but there wasn't much else going on)
Leaves Eyes
EDGUY
Devin Townsend
Korpiklaani
Doro
GWAR
TWISTED FUCKING SISTEEEEER!!!!

Best acts for me were Powerwolf and Twisted Sister. They are also the only two bands to my knowledge that got an Encore. Definitely going back next year!
