For more than two decades, Lettuce have brought a new vitality to classic funk, matching their smooth and soulful grooves with a hip-hop-inspired urgency and mastery of beat. Now, on their fourth studio album Crush, drummer Adam Deitch, guitarists Adam Smirnoff and Eric Krasno, bassist Erick "Jesus" Coomes, keyboardist Neal Evans, saxophonist Ryan Zoidis, and trumpet player Eric Bloom deepen that sound by channeling the sonic freedom and infectious energy of their incendiary live show.
