Tomorrow evening, Sept. 4th, is the world premiere of a new documentary, Jimi Hendrix: Electric Church, on Showtime.

As previously reported , “Directed by John McDermott, the film captures the guitar legend’s performance at the Atlanta Pop Music Festival in July of 1970 — just two months before his death.

During the performance — which was his largest ever in the U.S. — Hendrix blazes through such classics as “Purple Haze,” “Freedom,” “Hey Joe” and his version of “The Star-Spangled Banner,” the latter against a backdrop of fireworks.

The documentary includes never before seen footage, plus interviews with Paul McCartney, Steve Winwood and Hendrix’s late, great drummer Mitch Mitchell.”

Jimi Hendrix: Electric Church will premiere tomorrow night at 8:00 pm CT on Showtime.
