Bear with me, I'm trying to post this via my phone as I'm out in Austin right now for SXSW.
Next week for DLC we have the much awaited Earache Thrash Pack. All tracks are $1.99 (160 Microsoft Points) or $5.49 (440 Microsoft Points) for the pack.
"Blinded By Fear" by At the Gates (master)
"Thrasher" by Evile (master)
"D.O.A." by The Haunted (master)
Credits available via the "DLC Credits" link at the bottom of the page.
On Tuesday check out rockband.com/life for stories and background on the tracks.
