Stevens sports a healthy fetish for Americana’s more unusual artifacts and anecdotes (he’s penned songs about Midwestern UFO sightings and John Wayne Gacy Jr.). On “The BQE,” he venerates the Brooklyn-Queens Expressway. His affinity for cinematic soundscapes means he has the chops to pull off an album that’s little more than a 40-minute orchestral suite. And while it’s dandy to think an artist wrung such fine-spun beauty out of a 13-mile slab of congested, unsightly roadway, “The BQE” ultimately feels self-indulgent and aimless.
