The two-LP live album Rock of Ages gets expanded beyond anyone’s expectations. The classic live double is issued here in two formats. One's a 29-track edition that includes one version of every song The Band performed over its four-night showcase at New York City’s Academy of Music in late 1971. The other “deluxe” version adds the entirety of the New Year’s Eve concert, remixed from the original soundboard tapes. Please note that 11 tracks from the New Year’s Eve concert are duplicated from the first batch of 29 tracks, including the four-song highlight with Bob Dylan. Despite these presentation quirks, the performances show The Band at its tightest, since it was obliged to meet the exacting standards of Allen Toussaint’s horn section. Naturally, things become less organized when Dylan shares the stage and The Band plunges into its unique brand of go-for-the-throat rock ‘n’ roll. It’s an essential piece of The Band’s history.
