Clinton Street Theater is the oldest continuously-operating movie theater in the northwest and one of the longest-running theaters in the country. Offering truly independent film and championing a variety of live events from music to modern dance, CST also offers their venue as a community space for nonprofits and local artists.

This month, the theatre celebrates its centennial and commemorates the 45th anniversary of the legendary three-day Woodstock music festival in 1969, and the 45th anniversary of Portland’s community radio station KBOO by screening two of the greatest concerts ever captured on film. Jazz On A Summer’s Day, the incredible film from the 1958 Newport Jazz Festival, and the Director’s cut of Woodstock. Both film showings are benefits for KBOO.

Woodstock screens August 18, at 6:30 pm. Director Michael Wadleigh worked with over 300 hours of footage to create his original 225-minute director’s cut (cut by 40 minutes for the film’s release in 1970).The version screened here has added performance footage from Jimi Hendrix, Crosby, Stills, Nash and Young, Janis Joplin, Jefferson Airplane and Canned Heat.

Jazz On A Summer’s Day screens August 14, at 7 pm and features electrical performances from Anita O’Day, Thelonious Monk, George Shearing, Gerry Mulligan, Louis Armstrong, Dinah Washington, Mahalia Jackson, Chuck Berry, Max Roach, Art Farmer, George Shearing and Eric Dolphy all performing on one miraculous and magic Saturday afternoon.

Both of these films are non pareil live documents of historical performances from a time when these kind of events could actually happen with musicians that defined their era. It’s the perfect way to chill in the Dog Days of summer as Clinton Street Theatre is now air conditioned. Read all the details at cstpdx.com and kboo.fm.
