Those folks at Primavera festival are really laying it on heavily with the additions of late. Only a couple of weeks ago a huge batch of acts playing next year were announced and now...there are more. Although not quite so many this time. So here, we present to you some bands who have just been confirmed via Primavera Sound's Twitter.

Harvey Milk
Melvins
Orthodox
Liturgy
Sleep
Wolves In The Throne Room
Napalm Death
Mayhem
Grimes
AarabMUZIK
Buffy Sainte-Marie
A.A Bondy
Mazzy Star
The Afghan Whigs (+ Optimus Primavera)
Justice

...and that's just the list so far. Much heaviness. The announcements seem to be ongoing. I mean, we think they've finished but can't be quite sure. This year's Primavera Sound takes place from May 30-June 3. More information can be found on the official website which really is quite helpful, even in English. There is also an edition of Primavera taking place in Lisbon, Portugal. That's called Optimus Primavera Sound and there's a great deal more information available here.
