This once-in-a-lifetime newgrass supergroup provides a unique showcase for the unlimited sonic possibilities of acoustic instrumentation. Featuring Jerry Douglas, perhaps the hottest Dobro player on the planet, who is taking time off from his “day job” backing up Alison Krauss to join the group; mandolin virtuoso Sam Bush, who brings his mile-a-minute, jaw-droppingly fancy fretwork; and holding down the low-end is the phenomenal double bassist Edgar Meyer, a musician as equally at home playing with Yo Yo Ma as with a bluegrass band. This is surely an acoustic music lover’s dream team!
