Unfortunately, a finger injury sustained shortly after joining the band meant that with Harris sidelined, for their 2023 UK tour at least, the DL03 consisted of Delvon Lamarr, with Josh Perdue on guitar, and Ehssan "Ace" Karimi on drums.

The band's music is rhythm-based and rooted in the 1950's, 60's and 70's soul-jazz, funk and blues styles, reminiscent of Booker T. & the M.G.
