James Brown Jr. will be joining The Blues Dogs at the penultimate concert of the 2014 Payson Park Music Festival tonight, Wednesday, Aug. 20 beginning around 6:30 p.m.

The Blues Dogs, which is a perennial visitor to the Festival, “is a collection of Boston mutts that all love to play the blues,” according to its website.

“That stuff that gets you to tapping your foot, nodding your head, and then just to shaking all over. Feeling good music.”

The quarter-century Payson Park Music Festival is held at Payson Park Playground at the corner of Payson Road and Elm Street.

The concert is sponsored by the Alper Family.
