Keen-eared gamers may have noticed that the TV commercial spot promoting the recently released Guitar Hero III: Legends of Rock prominently features a song that isn't actually in the rhythm game. Activision is remedying that today, as the publisher is releasing a downloadable content pack including that track--Velvet Revolver's "Slither"--as well as two more from the rock supergroup, and a trio of Foo Fighters songs in a separate pack.
The two packs are now available on the Xbox 360 version of the game for 500 Microsoft points ($6.25). Activision is saying that the same packs will be made available for the PlayStation 3 version of the game later this month. However, a Sony representative told GameSpot both packs will be going up with today's PlayStation Network release, and will carry a price of $6.25 each.
In addition to "Slither," the Velvet Revolver pack contains "She Builds Quick Machines" and "Messages," from the band's regular and deluxe releases of Libertad, respectively. The Foo Fighters pack includes "The Pretender" from Echoes Silence Patience & Grace, "All My Life" from One by One, and "This is a Call" from the band's self-titled album.
