This is the time of year when every high school choir, church choir and community choir hold seasonal concerts and try, basically, to sound like Chanticleer
. Probably the greatest living male chorus, the multiple Grammy-winning group has recorded and performed jazz, spirituals, Gregorian chants and more; their annual December holiday tour is a tradition that’s impossible to mock—unless you want to make the same old tired jokes about men who can sing really high having no testicles. They bring pure vocal beauty on Sunday, Dec. 12, at the Napa Valley Opera House. 1030 Main St., Napa. 5pm. $30–$52. 707.226.7372.
