Rumours of the music game's death were greatly exaggerated, it seems. Genre heavyweight Harmonix has just announced Rock Band Blitz for Xbox Live Arcade, a multi-lane revamp which resembles PS2 classics Rez and Amplitude.
You'll be able to import all your existing Rock Band DLC tracks to Blitz, assuming the 25 songs on-board don't cut the mustard. Gameplay involves skipping between lanes to keep the instrumental, vocal and percussion parts in sync. You'll do all this with a controller - there's nary an oddly shaped peripheral in sight.
Here's the announcement trailer. Rock Band Blitz launches in summer 2012.
