The music is mostly notated, but in a large-scale dual cadenza Chase and Spalding improvise together, remarkably responsive, unified and relaxed, creating a miniature universe of sounds — whispery, earthy, otherworldly-woozy, underwater-translucent, simple and raucous: a paean to the joy of collaboration, of play.
The orchestra, led by Mälkki with focused confidence on Wednesday, tends to be active but subdued, the way you can perceive seething activity even in a seemingly still jungle. There are hazy effusions of brass; little thickets of rattling, shivering percussion; and whooshing, glistening strings that were a textural link to the Ives, as well as to Stravinsky’s “Petrushka,” which came after intermission.
Performed in the pared-down orchestration Stravinsky made in 1947, decades after writing the piece, “Petrushka” here seemed both to echo and to have generated the Lara concerto’s off-kilter abruptness, fearless colors and wry enigmas.
The Philharmonic, sounding poised throughout the concert, was especially evocative in Stravinsky’s humid third tableau. Alison Fierst brought nuance and a sense of mystery to her crucial solo on, yes, the flute. (The instrument could hardly get a more profound showcase than this program.) Under Mälkki, “Petrushka,” more than any other quality, had unexpected intimacy.
As did Lara’s concerto. Even as it builds to flourishes of gleaming Hollywood-golden-age grandeur, and even with substantial forces — there are two full string sections onstage, one tuned slightly higher than the other — Lara has the maturity to resist doing too much.
He also has the skill to shape a gorgeously varied but unbroken single movement that evolves organically over its 30 minutes to a final lullaby, pricked by starry harp. This is a complex but legible, lovable piece; a funky yet elegant ritual; thrilling and taut, if also fundamentally unhurried and unpressured.
Spalding performed in a jumpsuit printed, in bold capital letters, with “LIFE FORCE,” and I felt that way about the music, too.
