Now we’re born again,” sings Zach Rogue on the closing track of Rogue Wave’s fourth studio album, Permalight. 　　 　　The dreamy acoustic lament lasts just over a minute but in sound and spirit it neatly sums up everything that comes before it. A punchy, deceptively effervescent set of multi-instrumental pop tunes, the Northern California band’s latest set represents a giant breakthrough for Rogue and his longtime musical partner, drummer-keyboardist-vocalist Pat Spurgeon. “The record sounds, for lack of a better word, fun,” the frontman says. It’s an astonishing change of direction, to say the least. Formed by Rogue in 2002 after he lost his tech job and parted ways with the Oakland rock group Desoto Reds, Rogue Wave has a reputation for crafting classic, inward-looking pop songs highlighted with psychedelic guitars, pastoral sound effects and intricate rhythms.
