The SERP trio combined near-professional aptitude with a unique playfulness performing before a packed Slosberg Recital Hall Sunday night, drawing from the oevres of Franz Josef Haydn, Paul Schoenfield and Johannes Brahms for their spring show. Comprised of pianist Josh Klein '07, violinist Graham Patten '07 and cellist Sidney Coren '07, the chamber trio crafted an eclectic program balancing two classical and romantic pieces with a more jazz-inflected, contemporary one.Emerging from Slosberg's wings, Patten and Coren began the evening without Klein, performing Haydn's "Duet for Violin and Cello," which, despite its light, breezy feel, provided the evening's most sober moments. Still, the duo's expertise remained evident; in the piece's tempo di menuetto movement, a series of call-and-response exchanges between the two instruments was expertly-crafted and seemingly effortless.

The two then retreated from the stage, returning moments later with Klein. With a "one, two" count and jarring, discordant opening notes, the trio began the evening's most dynamic piece, 20th century composer Schoenfield's "Caf Music," a vibrant, jazzy and often schizophrenically eclectic piece evoking the setting described by its title.

The piece's allegro movement captured the mood of a bustling nightclub, while the contemplative andante moderato portion first hinted at an evening's drunken comedown, and then at the next morning's epiphanic wake-up. Its final presto movement recast the first portion's up-tempo themes in a volatile-even violent-framework.

While "Caf Music" was the crowd's favorite piece, Brahms' subtle, ambient "Trio No. 1 in B Major" was the evening's most epic and expansive.

While the show's first half emphasized each member's individual talents, the Brahms piece was far more restrained: No instrument ever overpowered another, and each crescendo was deliberate and slow-building. As the final climax of the allegro movement ended, the three musicians rose in relief, each wiping their sweaty brows as the audience stood in adoration.
