Peter and the Wolf, I’ll admit, was kind of charming, when I was a 7-year-old working-class kid slathering on sophistication like calamine lotion. But that whole Michael Tilson Toffeenose sort of enriching the runny-nosed masses doesn’t wear so well when you’re a grown-up: A real live classical musician has deigned to enter our humble tavern with his fancy-ass instrument! Hold your belches, boys! But I’d like to believe that Matt Haimovitz isn’t just showing off for us non–Premio Internazionale “Accademia Musicale Chigiana” awardees—or trying to get press like the subhead in the New York Times: “He Was to Be the Next Yo-Yo Ma. Why Is He Playing Local Dives?” And I can get behind that belief because I’ve heard the young cellist fill Iota with the richness of Bach’s solo cello suites. It’s an intriguing experience, to take in not only the sound coming from Haimovitz’ 18th-century instrument but the whole atmosphere of people listening and responding. James McMurtry, a very different Iota artist, said of making a live album that the audience “becomes another instrument,” and it’s a point worth remembering even when that audience hovers in rapt silence, cigarette ashes expanding. But the proof, ultimately, of Haimovitz’s mission to play classical music in nonclassical venues is in the music itself. His new album, Goulash!, is “a BartÓk-infused stew.” Expect lively music, some unexpected mashups, and—trust me on this—a good time when UCCELLO plays with Haimovitz at 7 p.m. Sunday, Dec. 4, at Iota Club & Cafe, 2832 Wilson Blvd., Arlington. $16.
