The term “bandleader,” with its sheen of the olden days, is used way too seldom, even with the jazz age wildly back in vogue (thanks a lot, Baz Luhrmann). But then again, you can’t name many who actually deserve that label. Ape School might be our city’s most deserving of that title. Michael Johnson, the man behind this colorfully-named outfit, has worked with everyone from Kurt Vile to the Lilys, and his career as a solo artist has been supported by a host of local luminaries. He’s joined at Johnny Brenda’s tonight by The Interest Group, an art-minded ensemble who give major credence to Philly’s utter disdain for convention.
