How distant the mid-1970s seem now. They were unkempt, hairy, hedonistic, improvisational, analog, inefficient — anything but neatly calculated and Instagram-ready. Post-psychedelic and pre-AIDS, they were a continuation of the idealistic, natural 1960s, yet they were also an immediate precursor to the polymorphous, synthetic, role-playing disco era. The bitterness of Vietnam and Watergate lingered; hippie utopianism was giving way to a more selfish search for individual satisfaction. Things were still scruffy, but not quite so communal.

The Rolling Thunder Revue, concocted by Bob Dylan, was precisely a manifestation of its era. Starting in Plymouth, Mass., where the colonial Pilgrims landed, it wandered the northeastern United States and Canada from fall into winter of 1975: a brief peregrination. In Dylan’s public career, which is now well into its sixth decade, it stands as his most peculiar tour of all.

Two new projects revisit the Rolling Thunder Revue in extensive detail. “The Rolling Thunder Revue: The 1975 Live Recordings” is a 14-CD, 148-track boxed set of music from the tour’s rehearsals and performances, vastly expanding the two dozen songs released on a 2002 collection, “The Bootleg Series Volume 5: Bob Dylan Live 1975, The Rolling Thunder Revue.” And on June 12, Netflix premieres “Rolling Thunder Revue: A Bob Dylan Story by Martin Scorsese.” It’s a not-quite-documentary that mixes 1975 tour footage (which was shot for the 1978 film “Renaldo and Clara”) and latter-day interviews with Dylan, Joan Baez and other Rolling Thunder participants, along with some fictional characters.

Both the boxed set and the film sprawl proudly and unpredictably, just as the Revue itself did. And both projects traffic in revelation and put-on, sometimes simultaneously. Onstage in 1975, introducing a then-new song called “Isis” that traces improbable adventures, Dylan claimed, “This is a true story. Actually, they’re all true.”
