Boutique booking agencies the Billions Corporation and Constant Artists Touring have merged.

Beginning Sept. 13, Los Angeles-based Constant Artists founder Ben Dickey will begin working as a booking agent for Billions. Dickey brings with him an eight-artist roster, including Explosions in the Sky, Black Joe Lewis & the Honeybears, Okkervil River and Suckers.

The management side of Constant Artists will not be affected by the merger, Billions president David "Boche" Viecelli tells Billboard.biz. Dickey will continue to work from Constant Artists' Los Angeles office located within the Wiltern Theatre building. A portion of that space will serve as the new Los Angeles branch of Billions.

Starting Monday, Dickey can be reached for Billions agency business by phone at 312-997-9999 (ext. 8250) and via e-mail at ben@billions.com.

In 2007, Dickey left his post as an agent at Ground Control Touring to open a new booking division at his management company Constant Artists, which represents Spoon and Mates of State, among others. Prior to Ground Control he owned Austin, Texas-based Falsetto Agency.

Headquartered in Chicago, Billions now employees 10 agents who represents such artists as Arcade Fire, Death Cab For Cutie, Nick Cave and the Bad Seeds, Sufjan Stevens, Vampire Weekend, Bon Iver, Neko Case, Silversun Pickups, Sharon Jones & The Dap-Kings, Fleet Foxes and the Swell Season. In addition to Chicago and Los Angeles, the firm has agents located in Seattle, Toronto, Portland, Ore., and Bloomington, Ind.

In 2008, Billions merged with agent Trey Many's Seattle-based Aero Booking. The merger brought in such acts as Death Cab For Cutie, the Postal Service, David Bazan, Midlake, Beach House, Bodies of Water and Bowerbirds.
