The Los Angeles group GospelbeacH's sound harks back to several eras of California music, from folk-rock and sunshine pop to country-rock and the paisley underground. Fronted by Brent Rademaker of Beachwood Sparks and filled out by like-minded friends, the band debuted with an album that respectfully lifted the spirit and sound of early-'70s Grateful Dead (2015's Pacific Surf Line,) then jumped ahead a few years to the jangling pop of Tom Petty & the Heartbreakers on 2017's Another Summer of Love.
