We do love contrast. Next week's Rock Band 3 update will include a downloadable "Days of Peace" pack, featuring patchouli-scented tracks from Blood, Sweat & Tears, Jefferson Airplane and Santana.

Next week's update will also bring a version of the infamous Guitar Hero face-melter "Through the Fire and Flames" to RB3. More importantly, and insanely, you'll be able to purchase a Pro Guitar upgrade for that track. That should take care of any lingering notion you had that you could actually play the guitar.
