ARLO GUTHRIE He’s had only one top-40 hit and hasn’t charted since 1981, but singer, songwriter, activist and comic raconteur Arlo Guthrie is still running strong with an illustrious recording and touring career. Building on the early trifecta of “Alice’s Restaurant,” “City of New Orleans” and beloved drug running anthem “Coming into Los Angeles,” he still maintains starry-eyed optimism leavened with wry humor. But darker material like “Victor Jara,” a plaintive paean to the Chilean activist murdered by a C.I.A. backed junta, prove that Arlo is just as much the fascist killing guitar slinger as famous father Woody Guthrie. A rare opportunity to see a national treasure. $33.50-$39.50. McGlohon Theatre.
