New Guitar Hero World Tour downloadable content was quietly announced recently.

First, a three-pack of Jimi Hendrix downloadable master tracks are available for Xbox 360 and PS3, including the blues track “If 6 was 9”, rhythm and blues classic “Little Wing” and a live version of the hit “Fire.”

Additionally, R.E.M. songs are available now for PS3 and Wii. The R.E.M. track pack features three songs, which can also be downloaded as singles (and singles only on Wii), from the band’s newest album, Accelerate, “Horse to Water”, “Man-Sized Wreath” and “Supernatural Superserious.”
