Bay Area Sacred Harp (BASH), the people I sing with most Monday nights, will be singing at the open house at Freight and Salvage Coffeehouse this Saturday. We’ll be there from 2-4 p.m. singing traditional 18th-20th C. American 4-part harmony — low-stress workshop, some instruction by BASH’s experienced singers, lots of (slow) singing, fun people to hang out with. And hey, it’s free.
