LAB sessions consist of 6 or so weeks of rehearsal, all day on Saturdays, then a series of performances for which LAB ( Louis A. Botto Choir) acts as Chanticleer's In-School Ambassadors, giving performances in Bay Area schools. LAB X ( which means that this is the l0th LAB session since we started it) began their performance round today at Santa Rosa High School. Santa Rosa H.S. has been the home school of quite a few LAB participants over these several years. Last Saturday, prior to their last rehearsal before hitting the road, LAB X attended the recital portion of our auditions.
