Saturday evening was the 60th anniversary of the first-ever St. Paul Chamber Orchestra concert, and champagne and treats were available in the Ordway atrium afterward.
Inside the hall it was business as usual — a U.S. premiere, two works by lesser-known composers, and a podium debut by a fast-rising young conductor.
The premiere was "Dark with Excessive Bright," a new concerto by the American composer Missy Mazzoli.
The title comes from Milton's epic poem "Paradise Lost" and pictures God in heaven, mysteriously cloaked and "throned inaccessible."
The unusual thing about the piece is not so much the title as the fact that it's for double bass — a bedrock of the symphony orchestra, but an instrument that barely gets a look-in when it comes to concerto repertoire.
Over a 15-minute span, "Dark with Excessive Bright" explored the bass' inner voice in music of eerie resonance.
Disorienting downward glissandos summoned an ambience in which traditional coordinates blurred and a netherworld of shifting mists and shadows was established.
Amid the swish of textures — the concerto is written for string accompaniment only — soloist Zachary Cohen hunched over his leviathan of an instrument, reaching low to find the highest notes on the fingerboard and digging primeval utterances from its inner recesses.
