If you like the cello - especially when it has nothing to do with composers who’ve been dead for 300 years - check out Cello Madness Congress. Reconvening this weekend for the first time in two years, this roving tribe of experimental musicians hits Eth-Noh-Tec theater to play their funky brand of classical hip hop. Think vocal percussion twisted with a sound that jumps from stately to ethereal to circus fanfare.

Joined by beatboxing extraordinaire CelloJoe and the kinetic storytelling of Eth-Noh-Tec theater, Cello Madness Congress is set to perform octets from British composer Ian Stewart and local composer Joowan Kim. 

April 9. Eth-Noh-Tec Theater, 977 South Van Ness Avenue. Tickets are $5-20 sliding scale at brownpapertickets.com/event/147083.
