"The madness runs in cycles," Tom Clarke sings forebodingly in "The Glow," one of the highlights of the U.K. duo Cloud Boat's second album. The music rushes along, propelled by the high-efficiency tick of a drum loop, but there's no trace of madness or even anxiety in his voice. Instead, Clarke radiates priestly calm as he gives listeners a set of vague, odd instructions: "Take some of these candles," he intones darkly, as if calling from some Middle Ages theater. "The glow will guide you."

You probably haven't been waiting around for some singer-songwriter to update Harry Chapin's inescapable 1974 hit "Cat's In the Cradle," the slightly cloying tune about the changing dynamic between parents and children over time. And if you did happen to be waiting for such a song, you probably wouldn't put Conor Oberst, noted sensitive indie-rock soul, in charge of writing it.

The creators of pop music are usually able to break down the fundamentals of their craft — that search for the clever rhyme, the killer beat, the singable chorus. They are less articulate, understandably, about the other quest, the one that powers those everyday searches: the pursuit of ecstasy in sound. There's something almost paranormal about that part of the creative process, yet we know those moments, instantly, when we hear them.

Every language has words and phrases that elude easy translation. In Portuguese, "saudade" (pronounced by Brazilians as "sow-DAH-djee") is one of those. Some musicians equate it with the blues; it's generally associated with melancholy and longing. In its most recent bio, the Washington, D.C., electronic duo Thievery Corporation defines it as "a longing for something or someone that is lost."

The thumbnail summary already circulating for Beck's 12th full-length album goes like this: It's a sequel to Sea Change, the brooding 2002 record frequently mentioned as his masterpiece.

It makes cosmic sense that Sun Structures, the debut album from Temples, arrives at the height of the current nostalgia wave associated with the 50th anniversary of Beatlemania and the British Invasion.
