Formed in 2003, Astrograss has continually stayed at the forefront of New York's lively acoustic music and bluegrass scene.   The band's self-titled debut album, released in 2005, showcases its unique sound: earthy, bluegrass-inspired yet decidedly un-twangy. Astrograss is equally passionate in its vocal harmonies and surging improvisations.   In concert, Astrograss wows audiences with an eclectic yet solidly rooted mix of original material, choice covers ranging from Jimmy Webb to Guns n' Roses, and foot-stompin', "yee-haw"-inspiring fiddle hoedowns.
