Groundation is a Fusion-Reggae band based in Sonoma County, California. It was established in 1998 by Harrison Stafford, Ryan Newman and Marcus Urani upon their meeting at the Jazz program at Sonoma State University. Groundation's music incorporates the lyrical struggle of Roots Reggae, the progressive musicianship of Funk/Jazz fusion, and other-worldly transcendental Dub. The 9-piece band creates an altogether new Reggae sound, featuring swirling horns, stout poly-rhythmics, and soulful harmony vocals.
