By the time the third album from the classic-rock-inspired AI outfit The Velvet Sundown landed on streaming services, it had become a media sensation—although that notoriety was more attributable to its post-human origins than any piece of its catalog. Released about five weeks after the act’s debut, Paper Sun Rebellion features more 21st-century-ready distillations of classic-rock ideals. The three-album output has revealed two major origin points: the blues-influenced proto-rock offered up by the likes of The Animals and The Yardbirds; and the acoustic-guitar-heavy, harmony-rich folk rock that bands like America and Crosby, Stills & Nash rode to fame in the early ’70s. The Velvet Sundown’s out-of-time vibe remains intact on Paper Sun Rebellion, which doesn’t stray from the project’s already familiar path despite a huge increase in public scrutiny. Perhaps one of the advantages of a “synthetic music project” is that fast-tracked fame can’t go to one’s head as easily as it can with human musicians.
