The bulk of next week's Rock Band DLC comes from Styx and REO Speedwagon -- a pair of bands that have a history of collaboration -- in addition to a few tracks from lesser-known rock act Hautewerk. The REO Speedwagon and Styx tracks will be available both individually and bundled in a seven-pack for $10.99 (880 Microsoft points), while the Hautwerk track pack will be priced at $5.49 (440 Microsoft points). All single tracks will go for the usual $1.99 (160 Microsoft points).
You'll be able to get your hands on the following DLC starting Tuesday, April 21 on Xbox Live and Thursday, April 23 on the Playstation Store:

"Blue Collar Man (Long Nights)" by Styx
"Renegade" by Styx
"Too Much Time on My Hands" by Styx
"Ridin? the Storm Out" by REO Speedwagon
"Roll With the Changes" by REO Speedwagon
"Take It on the Run" by REO Speedwagon
"Can?t Stop Rockin'" by Styx and REO Speedwagon
"Stop Start Again" by Hautewerk
"Alone in My Head" by Hautewerk
"I Know Where You Came From" by Hautewerk
It's kind of a shame that the Styx and REO Speedwagon tracks aren't also being released in separate three-packs. Then again, are there really that many REO Speedwagon fans out there who don't also enjoy some Styx from time to time?
