Mark Wilder had already worked with Tim Geelan on the remixing of the 1960s Columbia outtakes on The Bootleg Series Volumes 1-3.

Wilder's name has also appeared on remastered CDs from numerous other Sony/Columbia artists, including Dave Brubeck, Miles Davis and Bloomfield/Kooper/Stills, and he is credited with "digital editing" on Dylan's Live 1966 release. More recently he remastered Dylan's 1960s mono albums for the CD issue of The Original Mono Recordings.
