The annual Rock USA Festival set for this summer in Oshkosh, Wis., has expanded to a four-day event this year, scheduled for July 17-20. The nonstop rock fest that promises to “break a few rules” just announced its lineup with an eclectic mix of headliners ranging from Avenged Sevenfold and Godsmack to Bret Michaels and Van Halen.

While several of the daily acts are still TBA, the current lineup for each of the four days is:

Wednesday, July 17: Saliva, Buckcherry, Avenged Sevenfold
Thursday, July 18: Slaughter, Great White, Queensryche, Bret Michaels
Friday, July 19: Sevendust, Chevelle, Godsmack
Saturday, July 20: Dokken, Jackyl, Ratt, Van Halen

This show marks the only live date on Godsmack’s touring calendar this year, thus far, as frontman Sully Erna previously announced that the band was mostly taking 2013 off while he worked on his solo music.

Meanwhile, there's a good chance that Avenged Sevenfold play a song or two off their upcoming album, which is expected this summer.

Boasting “the lowest festival ticket price in the Midwest” for a limited time only four-day passes are on sale for a mere $49. This sale one runs March 11-13 so head over to the event’s official website for more info on ticketing and campsites.
