“The Errant Charm” is a superb soundtrack for an afternoon idyll. Vetiver bandleader Andy Cabic spent hours wandering the streets around San Francisco’s Richmond District, listening to rough mixes, tinkering with lyrics and arrangements. The album opens with “It’s Beyond Me”, a slow boil of acoustic guitar and vintage keyboards over a roomy beat. Here you’ll encounter almost every sonic idea showcased on “The Errant Charm”, the album’s universe distilled into one vibrant song.
