The Bob Dylan catalog is the next major work scheduled to get a sonic upgrade. Columbia/Legacy plans to release 15 titles on hybrid Super Audio discs.

The discs will be Sony Music’s first releases in the format, which was unveiled last year with the release of the Rolling Stones’ early works.

Releases are slated for Aug. 19 — though they could be pushed back a week — on the heels of the release of the film “Masked and Anonymous” and its soundtrack on July 25 and 22, respectively. Dylan stars in the film and performs four songs on the soundtrack.

Being released on hybrid SACD will be “The Freewheelin’ Bob Dylan” (1963), “Another Side of Bob Dylan” (1964), “Bringing It All Back Home” (1965), “Highway 61 Revisited” (1965), “John Wesley Harding” (1967), “Nashville Skyline” (1969), “Blonde on Blonde” (1969), “Planet Waves” (1974), “Blood on the Tracks” (1975), “Desire” (1976), “Street Legal” (1978), “Slow Train Coming” (1979), “Infidels” (1983), “Oh Mercy” (1989) and “Love and Theft” (2001).

Six titles — “Blonde on Blonde,” “Another Side of Bob Dylan,” “Bringing It All Back Home,” “Blood on the Tracks,” “Slow Train Coming” and “Love and Theft” — also will be issued as 5.1 multichannel releases with accompanying stereo mixes.

Hybrid Super Audio CD discs feature a high-density layer that can provide high-resolution multichannel surround sound in addition to a separate two-channel stereo SACD version of the same music, and a layer with a CD version of the recording.

Dylan, who has toured relentlessly for nearly a decade, announced a 22-concert summer tour last week that will begin July 12 in Winter Park, Colo., and will include a stop at the Pacific Amphitheater in Costa Mesa July 27.
