John performs regularly in a variety of ensembles, including the following:

Olson/De Cari Duo — A husband-and-wife ensemble dedicated to expanding the repertoire for classical guitar and voice, deriving inspiration from their eclectic backgrounds in both science and the arts. Their first CD, Quiet Songs, features Baroque and twentieth-century repertoire for solo guitar and guitar and voice. Their new recording, Eve's Diary, will be released October 12, 2018, and will feature new compositions and arrangements written for the Duo, by David Leisner, João Luiz, Frank Wallace, and Clarice Assad.

Brooklyn Guitar Quartet — An ensemble of four experienced classical guitarists, dedicated to exploring contemporary, classical and popular repertoire. Recent recital programs have included transcriptions of piano music by Felix Mendelssohn and contemporary works of Leo Brouwer, as well as popular Brazilian rhythms by Paulo Bellinati. The quartet's aim is to communicate with its audience by choosing repertoire that is accessible while remaining substantive as works of sounding art.

Contemporanea Guitar Duo — A collaboration with guitarist Isabella Abbonizio, dedicated to performing vibrant and engaging contemporary repertoire for two guitars, with an emphasis on twentieth- and twenty-first century European music.

New York City Guitar Orchestra — A performing collective that unites all levels of musicians with a passion for exploring ensemble music in the unique context of the guitar orchestra. Established by the New York City Classical Guitar Society and directed by Jason Sagebiel, the NYCGO is a welcoming and professionally-run organization dedicated to providing valuable ensemble experience for guitarists of diverse backgrounds, while maintaining musical excellence and a commitment to fostering the creation of new music.
