Time for a blast from the past (40 years back, in fact). Two songs from The Edgar Winter Group's 1972 album They Only Come Out at Night, "Free Ride" and "Frankenstein" are making their war to Rockband 3 on January 17th (January 18th EU). Both songs offer keyboard support included in your $1.99 download, and "Frankenstein" offers Pro Guitar and Pro Bass upgrades for an additional $0.99.

Skipping forward another 25 years, we are getting two new songs from KoRn as well, for those of you (myself included) who enjoy metal. From 1998's Follow the Leader we get "Freak on a Leash", and from 1999's Issues, "Falling Away from Me". No keyboard support or Pro upgrades for these two, unfortunately.
