The Moore Brothers’ sixth studio album, California Sister, finds Thom and Greg Moore fronting a full band again. Not since their 2002 sophomore LP, On & Out, have their gossamer sibling harmonies hovered over electric guitar, bass, and drums. Greg fronts the gauzy opener, “Second To,” before Thom takes the lead vocals in “Heartattack,” a snappier tune with complex arrangements that move in sync with the easy cadence of his melodies. Greg’s “You Might Be My Baby” shows his uncanny knack for penning the perfect love song. But his gorgeous, sun-flared “Old Lady” is the album’s standout serenade. Here, his melodies melt down the song’s chorus like ice cream on a summer afternoon as he gently coos: “We’ll get blueberry flames/We’ll grow vampire eyes/We’ll be smiling at dogs/Be my old lady.” It’s one of those close-harmony songs that inevitably get The Moore Brothers compared to Simon & Garfunkel, even though Greg and Thom’s voices braid more closely than Paul and Art’s. The indie folk gem “Women and Men” is equally sophisticated and beautiful.
