Who doesn't love the Brandenburgs? We're talking, of course, about those six spunky concerti by J.S Bach that have weathered the centuries to become among the top 100, or maybe even top 10, most popular classical works of all time. Each of the Brandenburgs features a different combination of instruments and has its own distinct personality. But all of them share the same infectious energy and glorious thematic landscape that's Bach at his most happily creative. This week, the experimental classical/contemporary ensemble wild Up gives the Brandenburgs a new spin in “recomposed” form, performed by “virtuosic strings, screaming piccolo trumpets, baritone sax and an electric bassoon.” Unlike the original Brandenburgs, each of the concerti is the work of a different composer from the group, so they'll be more like six different pieces than six members of a set. Would Bach approve? Well, these wild guys figure they've got the go-ahead because Bach had intended for the concerti to be improvised, as was the style of the day in the baroque era. Sounds like a plan. At the Hammer Museum Courtyard, 10899 Wilshire Blvd., Wstwd.; Sat., Sept. 1, 3-5pm; free. (310) 443-7000, www.hammer.ucla.eduwww.hammer.ucla.edu. –Mary Beth Crain
