Princeton Festival switched gears this past Thursday night to chamber music with a return visit from the popular ensemble The Sebastians, which draws its moniker from the middle name of towering Baroque composer Johann Sebastian Bach. Surmising that Bach might actually have been called “Sebastian” by his friends, the instrumentalists first came together with the goal of playing “mixed chamber music at a high musical level, with friends.” Twelve members of The Sebastians came to Princeton’s Trinity Church last Thursday night as part of Princeton Festival, performing music of their namesake, as well as Bach’s contemporaries. Demonstrating the range and capabilities of 18th-century strings, flute and harpsichord, the conductor-less chamber orchestra showed how Bach’s influence is still felt to this day.

Although German composer Georg Philipp Telemann was more recognized than Bach in his own lifetime, his music was overshadowed by other 18th-century composers until the early 20th century. Since then, his music has been recognized as equally complex and intricate as the more well-known Bach and Antonio Vivaldi. Telemann’s Concerto in A Major for Flute, Violin and Cello was initially published in a collection known as “musique de table,” in the tradition of musicians performing while guests were enjoying a meal. The Sebastians began Telemann’s four-movement work gracefully, with David Ross’ Baroque flute providing a richer and more mellow sound than its 21st-century counterpart.

The combination of a slightly lower Baroque pitch, warm period instruments, and animated music seemed to bring down the temperature on a sultry evening as the ensemble created its own world of precise rhythms and tapered phrase endings. Joining Ross as Concerto soloists were violinist Daniel Lee and cellist Ezra Seltzer. All players watched one another well, with each soloist providing clean melodic passages. The second movement “Allegro” featured Lee and Seltzer in duet under extended trills from Ross. A courtly third movement showed Seltzer plying a wide-ranging cello line, while the light orchestration enabled the audience to hear Kevin Devine’s excellent harpsichord accompaniment.

Violinists Lee and Nicholas DiEugenio were showcased in Telemann’s Gulliver Suite for Two Violins in D Major, inspired by Jonathan Swift’s 1726 satirical novel Gulliver’s Travels. Throughout this narrative piece, Lee and DiEugenio frequently played in pure thirds, effectively bringing to life the Laputians and Lilliputians through fleeting passages played with precision and a bit of humorous acting at the close.

The Sebastians are known for Bach, and even with one Brandenburg Concerto cut from Thursday’s program, there was plenty of the Baroque master to enjoy. Concerto No. 6 in B-flat Major was the only one of Bach’s set of six pieces that did not use violins; the composer scored the three-movement work instead to feature two violas da braccio, which were relatively new at the time and which were expertly played in this performance by Jessica Troy and Kyle Miller. The orchestration often juxtaposed the violas against two more familiar violas da gamba, stylistically played by Matt Zucker and Adrienne Hyde. The Concerto’s key of B-flat and the absence of violins kept the texture mellow, as Troy and Miller maintained a lively dialog with cellist Ezra Seltzer and the two da gambas provided a solid foundation to the sound. Cadences were short and clean, and phrases well tapered. The third movement gigue-like “Allegro” was chipper without being too fast, and was especially noteworthy for Seltzer’s nimble cello lines.

The closing Brandenburg Concerto No. 3 in G Major brought the strings of The Sebastians to the stage, with the resulting performance being energized and refreshing. Quick thematic passages were passed down the row of violins and then to the violas, and the instrumentalists showed uniform dynamic contrasts. The second movement “Adagio” was originally composed as only two notes, with the intention that players would improvise a bridge between the two faster movements. Violinist Lee provided a quick improvisation over the two harmonic chords, before the orchestra was off to the races again to close the concert in spirited 18th-century fashion.
