- Red Hot Chili Peppers - "Snow (Hey Oh)"
- Red Hot Chili Peppers - "Tell Me Baby"
- Rush - "Closer to the Heart"
- Rush - "Working Man (Alternate Take Master)"
A cover of Rush's "Working Man" was previously released as DLC this past January.
"This version, however, is an alternate-take master from the same session [Rush] recorded the hit with an alternate solo," Harmonix's Sean Baptiste explained on the game's forum. "It has never been released."
Individually priced at 160 Microsoft Points ($2) a piece, each master track will be available for download from the Xbox Live Marketplace beginning Tuesday, July 8.
As usual, the PlayStation 3's online PlayStation Store will receive the songs on the following Thursday, July 10.
