Over 50 years ago, the pun-toting jazzman Mose Allison first laid out his cerebral troubles in a song called “Lost Mind.” “If you could be so kind / To help me find my mind,” he deadpanned in trademark bluesy inflection, “I’d like to thank you in advance.” Now 82, the wry pianist and singer appears to have finally unearthed his elusive treasure. “My Brain” opens his most recent album, The Way of the World, and in copping the form and melody of “My Babe,” a hit for Little Walter, he sings, “My brain is always ticking, my brain / Long as I am alive and kicking.” The album is recorded with an organic, warm tone and is another success for his new home, Anti-Records, who’ve regenerated the careers of Merle Haggard, Bettye LaVette, Rocky Erickson and Mavis Staples. Allison is always on the road, playing with pick-up bands in each city, and he plays an afternoon show on Sunday, Sept. 26, at the Napa Valley Opera House. 1030 Main St., Napa. 4pm. $25–$30. 707.226.7372.
