50 years ago tonight, the Grateful Dead set up shop at the Electric Theater in Chicago, IL for a thrilling two-set performance in “The Windy City.” Parts of the show would ultimately go on to be officially released as the 26th edition of the Dick’s Picks live album series, and after listening to the concert from start to finish, fans will understand why.

The performance that night came just a few months prior to the release of Aoxomoxoa, although the band made sure to include nearly all of the songs from the then-forthcoming album into the two sets, including “Dupree’s Diamond Blues”, “Mountains of the Moon”, “St. Stephen”, “Doin’ That Rag”, “China Cat Sunflower “, and “What’s Become of the Baby”. The first half performance also heard Ron “Pigpen” McKernan throwing in some additional verses into his performance of “It Hurts Me Too”.

The show that night also included a mix of tunes which the band regularly performed in the early, “primal-Dead” era of the 1960s. The first set featured some early-Dead favorites, including “The Other One” and “The Eleven”, Pigpen’s trademark blues tune “Turn On Your Love Light”, and “Morning Dew” (although the latter was left off the official Dicks Picks release). The second half of the show also included a drum solo from both Bill Kreutzmann and Mickey Hart, an 11:00-minute “Viola Lee Blues”, and a lovely a-cappella version of “And We Bid You Good Night” to close out the show.
