It takes a big choir to do justice to the music of Johann Sebastian Bach. Fortunately, the Hampshire Choral Society currently clocks in at 160 voices. The amateur group (they even assure prospective members their auditions are "non-threatening") is taking on the challenge of Bach's gorgeous but far-from-easy Mass in B Minor this week. They've been rehearsing the piece since January, so be prepared for a rousing rendition.
June 15, $10/students and seniors, $15/general, 3 p.m., John Greene Hall, Smith College, Northampton, www.hampshirechoral.org.
