A musical—and real-life—marriage of Susan Tedeschi's rough-hewn, bluesy vocals and Derek Trucks' virtuoso slide guitar, the Tedeschi Trucks Band provides a progressive take on the Southern rock tradition. Heartfelt balladry such as "Midnight in Harlem" and "Calling Out to You" set up the pins for the Bonnie Raitt-esque uptempo choogle of "Made Up Mind". Stax-Volt horns bolster Trucks' endlessly inventive and emotional soloing in epic live workouts like "Keep On Growing". And vocalist Mike Mattison mixes things up during "Get What You Deserve", a reproachful boogie.
