Childs takes Nyro's emotionally direct songs and gives them orchestral room to breathe.
Map to the Treasure opens with a wide, unhurried sweep of strings and piano, the kind of sound that sets the room before a single melody arrives. Billy Childs wrote and arranged these pieces around the songs of Laura Nyro, and the textures lean chamber-like: cellos, violins, a harp, and a rhythm section that moves with restraint rather than swing for its own sake. Tempos stay mostly relaxed, and the mood is reflective, warm, and a little melancholy.
The record is less about jazz improvisation than about arrangement. Childs keeps Nyro's melodic lines intact and builds layered settings around them, with Wayne Shorter's soprano saxophone adding a lyrical, searching voice and Chris Potter's tenor bringing more muscle where the writing asks for it. Yo-Yo Ma's cello gives several passages a grave, singing quality. Brian Blade and Vinnie Colaiuta handle the drums with a light touch, keeping the pulse present without pushing the pieces forward too hard.
As a place to start with Childs, this is a good choice. It shows his skill as an orchestrator and his affection for songwriting outside the standards tradition, and it is more accessible than his denser large-ensemble work. Listeners who know Nyro will hear what he finds in her material; those who don't will still get a graceful, carefully made record that rewards patient listening.
