Folksy singer-songwriter Birdie Busch is teaming up with jazz/electronic virtuoso Charles Cohen to perform a show across Philly on an open-top double decker bus on September 12th. In January, Busch released her last record, Birdie Busch and the Greatest Night, and it was XPN’s February CD of the Month. Charles Cohen, another long-time local musician, has been making jazz and experimental electronic music on his famous vintage Buchla Music Easel for decades. The two will play sets on the bus from 8 to 10 p.m. Boarding begins at 7:45 p.m. on the corner of 5th and Market Streets. Go here for more information on the event. Meanwhile, check out the stellar track “supermoon” from Birdie Busch’s new album and watch Charles Cohen mastering the music easel below.
