Once again, SoFA District hotspot Cafe Stritch is celebrating the man whence their name came, multi-instrumentalist and jazz innovator Rahsaan Roland Kirk.

Kirk, whose birthday falls on August 7, was known for playing for playing multiple instruments simultaneously, including an unusual straight alto sax variant called a stritch, Cafe Stritch’s namesake. (Kirk’s “Theme for the Eulipions” gave Stritch’s previous incarnation Eulipia its name, as well.)

Up until his death in 1977, Kirk produced a wide-range of jazz from mainstream to the experimental. His pioneering work has been cited as influential by musicians working in many different genres since.

To celebrate Kirk’s birthday and legacy, Cafe Stritch is holding the second annual Rahsaanathon, with a three-stand with house band the Eulipions, plus trombonist and Kirk-collaborator Steve Turre playing Turre’s arrangements of Kirk’s music.

The Rahsaanathon will also see poet Betty Neals, who co-wrote “Theme for the Eulipions,” perform the song live with the band. Closing the festivities will be a special edition of the weekly Eulipions Jazz Jam featuring performances of song’s from Kirk’s The Return of the 5,000 Lb. Man. And with the San Jose Jazz Summer Fest going on, some masterful jazz performers from out of town might just show up.
