Prince George’s County has the blues—and not only due to its ongoing struggles with violence and club shutdowns. Today brings the free and cleverly programmed Bluebird Blues Festival, now in its 19th year. This time around, the New York-based, Virginia-raised Holmes Brothers, pictured, occupy the headlining slot. They stray from archetypal Mississippi or Chicago blues, opting instead for gospel-inflected, juke-joint originals and adeptly arranged covers of Cheap Trick, Nick Lowe, and Tom Waits tunes. Local harmonica blower Phil Wiggins, performing with West Virginian blues player Nat Reese, is another highlight; so, too, are longtime girl group the Jewels and neo-soul vocalists Avery Sunshine and Carolyn Malachi.

The Bluebird Blues Festival runs from 12:30 p.m. to 6 p.m. at Prince George’s Community College, 301 Largo Rd., Largo. Free. (301) 336-6000.
