How's this: an 'educative' version of Rock Band, in which players are required to reconstruct slightly more difficult numbers. On the easiest difficulty setting, this includes Cage's 4'33". The second-highest setting includes Mauricio Kagel's Match, Faust's Concerto for Voice and Machinery, and the entirety of AMM's hour-plus 'Newfoundland'. Pity the poor guy who has to pretend to be John Tilbury. Worse yet is the final difficulty setting: Cornelius Cardew's Treatise.
