The 50th Anniversary Edition box set also includes five outtakes and alternate recordings from the Big Pink sessions and a previously unreleased a cappella version of I Shall Be Released. Exclusively for the box set, Clearmountain has also produced a new 5.1 surround mix for the album and the bonus tracks, presented on Blu-ray with the new stereo mix in high-resolution audio (96kHz/24bit). All the new audio mixes have been mastered by Bob Ludwig at Gateway Mastering.
