Though charcoal drawing was once the dominant artistic medium in America, precious few masterworks survived the realization that those early portraits could be crumpled up and used to smoke delicious stacks of ribs. Honor forgotten artists with today’s Groupon: for $10, you get two general admission tickets (a $20 value) to Ribs on the River 3 at the Trib Total Media Amphitheatre, presented by Drusky Entertainment. Choose from the following dates:

• Friday, June 17 at 5:30 p.m. featuring Ace Frehley
• Saturday, June 18 at 3 p.m. featuring Kenny Wayne Shepherd
• Sunday, June 19 at 1 p.m. featuring Leon Russell

Dedicated to promoting local and national concerts, Pittsburgh-based Drusky Entertainment presents Ribs on the River 3, a three-day festival and cookout. Along with a different line-up of 10 or more professional tune-makers each day, each night features a special headliner; Kiss's original spaceman Ace Frehley headlines Friday night, bluesman Kenny Wayne Shepherd tops the bill on Saturday, and rock icon Leon Russell melts any remaining intact faces on Sunday. Guests can keep fingers sticky to avoid dropping a beverage or concert program courtesy of renowned barbecue vendors including Florida Skin and Bones, Butch's Smack Your Lips BBQ, and Sgt. Oink's, who serve up saucy, slow-cooked eats throughout the show.
