Gravitational Forces is an album by Texas-based country/folk singer-songwriter Robert Earl Keen. It was first released in the United States on August 7, 2001, on Lost Highway Records. One reviewer described this album, Keen's ninth, as being "just a hair more to the country side of the folk-rock-country axis than ever before." Indeed, producer and multi-instrumentalist Gurf Morlix, and the various long-time members of Keen's own road band did not shy away from including fiddle solos and steel guitars in the mix when they suit Keen's songs. "I wanted to keep a real natural, organic sound," says Morlix, "My job as producer varies from artist to artist. I help them find the sound they want and then do what it takes to get that on record."
