During the winter months of 1978, Bob Dylan conducted rehearsals for his upcoming 115-date world tour in downtown Santa Monica's aptly named Rundown Studios. Captured for posterity by engineers Arthur Rosato and Joel Bernstein, the Rundown tapes represent a remarkably panoramic window into Dylan's creative process as he reinvents his classic songs via improvised lyrics and arrangements that gradually transform the raw, fiery melodies into larger-than-life pop fantasias seemingly earmarked for the casino ballrooms of Las Vegas. The four-CD bootleg box set The Rundown Rehearsal Tapes is an embarrassment of riches for the serious Dylan enthusiast, encompassing virtually every landmark in his storied songbook as well as some new compositions and a handful of traditional blues standards that never made it past the rehearsal stage.
