This weekend, join Terry David Mulligan for a deep dive into the electric new album by Tedeschi Trucks Band.

Derek Trucks joins Mulligan Stew this Saturday to chat about everything that went into creating Signs, the fourth studio album from the twelve-piece blues group.

Signs is a work with a whole lot of history behind it. The band lost four close friends over the course of recording: mentor Col. Bruce Hampton, Derek’s uncle Butch and Leon Russell (of Mad Dogs and Englishmen) and Greg Allman.

The album’s final track, “The Ending, is a touching honour to the four, one that Derek says the band will likely never play live as it is “too close to the bone.”

TDM and the guitarist also explore “Shame,” about the political turmoil in the U.S. from the perspective of a deep-south band.

Tune in to Mulligan Stew this weekend for a great interview and to hear five tracks from the album Saturday at 5pm MT. And check out the complete interview on the Mulligan Stew podcast, available on iTunes.
