According to a blabbermouthmouth article:
AS I LAY DYING, GWAR, IN FLAMES, TRIVIUM, CANNIBAL CORPSE, TERROR, THE BLACK DAHLIA MURDER, BEHEMOTH, THE CHARIOT and THROUGH THE EYES OF THE DEAD have been confirmed for the second installment of Sounds of the Underground tour, according to MTV.com.
The Sounds of the Underground organizers are taking a different approach to this summer's festival by keeping the number of bands on the bill down and extending the length of set times. Last year most bands got no more than 30
More bands will be announced in the coming weeks.

I hate festival shows though, I'd rather just see Opeth tour again.
