by Stephen Thomas ErlewineRusted Root's debut album is an agreeable collection of post-hippie folk\u002Frock. Drawing from The Grateful Dead, Phish, and Graceland-era Paul Simon in equal measures, the band can certainly work a low-key groove, spinning out solos and singsong melodies at well. They haven't perfected their songwriting yet -- many of the songs sound underdeveloped -- but their music sounds mature and hints at their potential.
