The Michigan History Project has unearthed several seven-inch reel-to-reel audio tapes recorded at a student ministry at the University of Michigan in 1968, including live performances by Neil Young, Joni Mitchell, Tim Buckley, Odetta, David Ackles, and Dave Van Ronk. The recordings came out of a countercultural hub in the 1960s, the Canterbury House in Ann Arbor, Michigan.

According to Rolling Stone, the Michigan History Project have acquired the special recordings and are in search of a record label interested in releasing them.

“We learned of the existence of the tapes about six years ago,” said Alan Glenn, President of the Michigan History Project. “They were in the possession of a private collector. Then they disappeared, and we were afraid they were gone for good. But a few weeks ago they resurfaced, much to our surprise and relief. Now our first priority will be to get them transferred to a digital format, then make sure that the original analog tapes are safely archived.”

Chris Goosman, Michigan-based mastering engineer, also said of the recordings, “These from Canterbury House aren’t audience-recorded bootlegs but first-rate soundboard captures made on professional equipment. It’s an amazing collection with the rare combination of being well-recorded and also well-preserved, and that makes it even more historically significant.”

The Michigan History Project also confirmed that the recordings were made with consent from the performing artists.

Neil Young performed at the Canterbury House on November 8, 9, and 10 of 1968, with the latter two nights featured on his Sugar Mountain – Live at Canterbury House 1968. Though, the November 8th concert has yet to see the day of light. According to Rolling Stone, “It’s unclear which date(s) the Michigan History Project is in possession of.”

Rolling Stone also notes that “Artists like Frank Zappa and the Mothers of Invention, Buddy Guy, Sun Ra, Richie Havens and more also performed at the Canterbury House during the era, but recordings of those gigs have not yet been found.”
