Only narrow-headed fools might grumble that Austin Blues Fest doesn’t have enough blues, when faced with a broad mix of gospel, second line brass, Afro-Cubanism, bounce, soul, jazz, funk, and zydeco that represents both the roots and outgrowths of America’s definitive genre. Purists will dig living treasures Buddy Guy and Bobby Rush (performing with Blind Boys of Alabama; see interview on p.16) as well as Jimmie Vaughan, while Cuban showstopper Cimafunk, NOLA bounce queen Big Freedia, and Southern soul septuagenarian Robert Finley are assured to elicit multi-generational dancing. Meanwhile, Houston-born pianist/producer Robert Glasper – who precedes Sunday’s headliner, Brittany Howard of Alabama Shakes – serves as ABF’s lodestar, synthesizing a variety of disciplines into one Black Radio. – Kevin Curtin
