"I think that the goal of any collaboration should be to come up with something that each individual wouldn't have come up with on their own, and I think that we've done that here," says Martin.

The album was produced by Peter Asher (James Taylor, Elvis Costello, Linda Ronstadt) and features bassist Esperanza Spalding, guitarist Waddy Wachtel, Nickel Creek alumni Sara and Sean Watkins and bluegrass combo the Steep Canyon Rangers.

"I fell in love with the banjo tunes because at first listen they evoked images and stories that were true to me," said Brickell.
