Undivided Heart & Soul produced by Dan Molad (Lucius) & McPherson, and developed largely in the studio (that studio being the historic RCA Studio B in Nashville), carries a sense of immediacy and irreverence. McPherson said, "Most folks know us for our take on vintage R&B and early Rock N' Roll. The past year, I've been digging so much into the heavier, brasher sounds of early Rock N' Roll... from bands like The Sonics, Link Wray, and into some early British Rock such as The Creation... these influences feature heavily in these songs.”
