The name Elephant Revival may sound like a witch doctor's work on a pachyderm, but it actually belongs to a Colorado folk quintet whose banjo, mandolin, fiddle and washboard mingle with guitar and bass to define a sound that weaves Scottish/Celtic music with indie rock and traditional ballads.
Lead vocalist Bonnie Paine's voice echoes a weary Sarah McLachlan and evokes images of sun-soaked summer afternoons in the South and contrasts nicely with bassist Dango Rose's Fred Schneider-esque vocals, Sage Cook's gravelly soul and Daniel Rodriguez's Jack Johnson purr.
The group also has a soft spot for the environment. They tour in a 1989 International School Bus powered by vegetable oil, which was Cook's brainchild.
