Previn's 1994 Trio for Oboe, Bassoon and Piano (replacing a previously announced premiere, rescheduled for an August Tanglewood concert) is an unapologetic bricolage. The opening movement, for example: chunky modal-jazz industry, some neo-classical repose, a lyrical central-casting love-theme, all fluently recombined. If the materials seem familiar, their employment is effortlessly dexterous - the slow movement's austere daisy-chain of solo piano and wind-duet paragraphs unfolds with unobtrusive deftness.
Previn's perfused piano tone - a soft, thick blanket of sound - informed a rich though somewhat unvaried sonic surface. But Ferrillo and bassoonist Richard Svoboda matched Previn's breezy confidence, smoothly tossing off the finale's dense riffs.
Previn later returned to the bench in Francis Poulenc's Sextet for piano and winds. Poulenc's effervescence still flummoxes standard Western associations of "deep" with "somber"; Steven Ledbetter's program notes described the Sextet as "hardly profound," but Poulenc's profundity is his holistic sympathy for the varied sustenance of the human soul, light and dark, holy and temporal, droll and rapturous. This performance also seemed studio-lit, the entire set in undifferentiated highlight and focus, though some faster sections, especially those featuring James Sommerville's high-wire precision horn, had more grit and bite.
In between those alloys was a distillation, Debussy's late-career Sonata for flute, viola, and harp, the composer recapitulating his lush style with spare, sure strokes. Elizabeth Rowe (flute), Steven Ansell (viola), and Ann Hobson Pilot (harp) offered a close-up reading in which isolated moments made the strongest impressions: the flute melting into the viola's initial entrance, the harp distantly tolling over the viola's rustic drone, flute and viola chanting amid a cascade of harp glissandi.
Brahms seems to have become the BSO's house red wine as of late; Sunday's concert closed with the G-major String Quintet, op. 111. For the most part, the players opted for extroverted, garage-band energy, a vehement brio, though the Allegretto third movement showed a polished restraint. The foot-stomping finale eventually brought discretion and vigor into diverting balance.
