Slave Ambient, the latest from The War on Drugs, is adorned with hazy blue-and-red artwork that suits the album’s warm, swirling sound. The Philadelphia band places a premium on production: Soupy, Spiritualized-esque atmospherics surround Adam Granduciel’s Tom Petty sneer, and even the tunes themselves meld together at times, softened by Eno-like sonic washes. Yet Slave Ambient is full of songs that would be right at home in the Bob Dylan songbook. If it all sounds vaguely familiar, it’s easy to get lost in—and high on—all the same. (Ryan Little) 9:30 p.m. at Red Palace. $10.
