These days, van Dyk and her bandmates are still proving as much: Their last several albums have seen them deepening their sweetly sloppy guitar-pop, looking beyond the Velvet Underground for inspiration (but not before releasing Bettie Serveert Plays Venus in Furs and Other Velvet Underground Songs, a live covers disc). On Serveert's latest, Attagirl, the band's seventh full-length, they dabble in polite disco-rock, streamlined Krautrock, live-band trip-hop, even mysterious film-noir surf-pop balladry. With its stylistic range and van Dyk's smart, sexy, sophisticated-lady performance, the album plays like a slightly more mature version of More Adventurous by L.A.'s Rilo Kiley, whose Jenny Lewis might've heard something of herself in Palomine. That's Bettie Serveert: out adventuring, so you don't have to.
