Howard Zinn is dead, but San Diego's Delta Spirit are among the many acolytes keeping the populist historian's ideas alive. Hence the band's stunning sophomore release "History From Below," which packages Zinn's concepts in melancholy folk-rock and crisp pop sheen.

Lead single "Bushwick Blues," which could be an old-school Ryan Adams track in its twangy live formation, gets a glossy metropolitan treatment on the album. In either instance the song is exemplary, showing the impeccably nuanced and natural songwriting at this band's core.

Such credentials virtually ensure a fine time at Wednesday's show, also featuring Ezra Furman & The Harpoons and The Romany Rye.
