After striking a national deal several months ago to program and promote music at about 20 Harrah's properties, Austin, Texas-based C3 Presents has locked down a number of artist bookings for the company's casino properties in the upcoming summer months.

Among the artists scheduled to perform are the Black Crowes, Journey, Bonnie Raitt, ZZ Top, Cake, Sheryl Crow, Stone Temple Pilots, Willie Nelson, the Roots, Regina Spektor, Elvis Costello & the Imposters, Gladys Knight with Al Green and Crosby, Stills & Nash.

Among the Harrah's venues C3 already books are the Stir Concert Cove at Harrah's Council Bluff and the Whiskey Roadhouse at the Horseshoe in the Omaha, Neb., market; the VooDoo Lounge at Harrah's in St. Louis and Kansas City, Mo.; and the Horseshoe Riverdome in Bossier City, La. Harrah's properties in California, Mississippi and North Carolina are part of the new deal.

"C3 has done a great job of building business and developing relevant programming for us," Harrah's Entertainment Corporate VP of entertainment Scott Schecter told Billboard. "We're looking forward to expanding the relationship to other venues throughout our system."

The deal does not extend into Las Vegas, where Harrah's works with AEG Live/Concerts West in programming the Colosseum at Caesars Palace and the under-development, 20,000-seat, $500 million Las Vegas Arena set to open in 2010.
