Do the math

If you placed a camera in live-music venues from downtown Sacramento to Orangevale, you’d notice one common theme: Nobody at the bar is paying attention. However, if you’ve ever attended a show at the artist-run Fools Foundation, chances are you went for the music. There’s no bar and no distractions; people convene there with the intent of listening. This Tuesday, instrumental math-rockers Don Caballero will hold court at the downstairs haven in support of their latest release, World Class Listening Problem on Relapse Records. Although drummer and co-founder Damon Che is the only original member left, this quartet still fires on all cylinders. Also along for the ride are Pennsylvania comrades Zombi, a crafty duo with an obvious penchant for Giorgio Moroder scores. O! The Joy opens the all-ages show. It all begins at 9 p.m. on Tuesday, and the cover is $6 with a mandatory, one-time $2 membership fee. Fools Foundation is located at 1025 19th Street, in the basement. I’ll be listening.
