Penn’s Peak announce JJ Grey & Mofro and Jonny Lang with North Mississippi Allstars will appear at 6:30 p.m. July 12.

From the days of playing greasy local juke joints to headlining major festivals, JJ Grey remains an unfettered, blissful performer, singing with a blue-collared spirit over the bone-deep grooves of his compositions.

It is hard to believe that at 36, Jonny Lang has already had a successful career for two decades.

Easier to believe when you learn he released his first platinum record at 15 — an age when many young people are just beginning to play music. “Lie to Me” revealed a talent that transcended the crop of blues prodigies floating around in the late nineties.

North Mississippi Allstars are back with “Prayer For Peace.” Founded in 1996 by brothers Luther (guitar and vocals) and Cody Dickinson (drums, piano, synth bass, programming and vocals), the now venerable band are entering their third decade with perhaps the most vital album of their career.

Tickets go on sale Friday at 10 a.m. at all Ticketmaster outlets, the Penn’s Peak Box Office and Roadies Restaurant and Bar. Penn’s Peak Box Office and Roadies Restaurant ticket sales are walk-up only, no phone orders.

Tickets are $48 for pit (standing at stage) and $38 for regular reserved. For more information on Penn’s Peak, go to www.pennspeak.com or call 866-605-7325.
