Nada Surf

“You Know Who You Are”

(Barsuk Records)

Expanded to a full-time quartet, New York’s Nada Surf continues to refine its glorious power pop on “You Know Who You Are.”

There’s a tinge of melancholy across much of the album, albeit with an optimistic if guarded outlook. The glass may be half full, but it’s a thimble, not a tankard -- “One day, I’ll love somebody else, one day, I’ll be good to myself,” Matthew Caws sings on “Believe You’re Mine.”

The bandleader co-wrote two songs with former Semisonic frontman and Grammy-winning songwriter Dan Wilson – “Rushing” and album closer “Victory’s Yours” -- whose vocals contribute to the latter‘s dreamy, Trip Shakespearean feel.

“Friend Hospital” shows Caws in an affecting mode, combining resignation and pained insight –- “So much better that we’re not together, ’cause I will not lose you, or be the blues to you.”

“Out of the Dark” celebrates minor achievements, its Tom Petty jingle-jangle and horn section elevating the can-do spirit, while on “Animal” Caws’ smooth, multi-tracked vocals slip into a vaguely Dylan-like diction.

The title track and “New Bird” pick up the pace and the rest of the band -- lead guitarist Doug Gillard now fully on board beside bass player Daniel Lorca and drummer Ira Elliot -- is as congenial as ever.

Pronounced nearly finished a year ago, the album underwent a series of recalculations until Nada Surf discovered a flowing route to like-minded listeners. You know who you are. (AP)
