What do 13 years of experience plus seven full-length albums plus a pair of twin brothers plus one lead singer add up to? In this case, the latest release from New York City alt-dreamers Blonde Redhead: their summery, melodic 23. With newfound energy, the trio maintains the sense of wonder from 2004’s Misery Is a Butterfly, but leaves much of the dark sentiment behind with intensive production and less raw intuition.

Unlike previous works, where beauty had to be dug from beneath deep moans and drowned-out sounds, 23’s beats and loops are accessible and captivating ­- which does wash some of the untraceable emotion that gives the group its mystery. Title track “”23″” tests new waters with echoing chord progressions, ceaseless drums and dizzying riffs under Makimo’s standard unintelligible words, a layered, repeated blur that avoids clutter and sets a mystical trance. The dream continues with the wind chimes and glockenspiel of “”Dr. Strangeluv,”” then takes a sinister turn as sudden gasps for oxygen pair with precise synth taps in “”The Dress.””

But once this familiarly surreal universe has been established, Redhead put new structural spins on their formula: Maracas and tambourines turn “”Silently”” from their usual haunt into a beach-friendly Cat Power-covering-Blondie ballad, and the sporadic beeps and chorus rounds of “”Top Ranking”” are fit for musical theater. But because of their fantastical instrumentation and imaginative placement, both stay cohesively afloat. 23 proves that being easily grasped doesn’t make something less enthralling, and with a new managability that doesn’t lose all its tricks, Redhead – indie as they may be – flirt dangerously near the charts.

Blonde Redhead will perform live at the Belly Up on April 27 at 8 p.m.
