Johnson Hall Opera House in Gardiner will welcome a trio of musicians — Béla Fleck, Edmar Castañeda and Antonio Sánchez — to the Reehl Stage at 7:30 p.m. Wednesday, July 30.

This new trio features instrumentation that the venue said “might safely be called uncommon.” Playing original repertoire, much of it collaboratively written, the group embarks on “fearless explorations that audiences will find irresistible — rich with strong melodies, gorgeous harmony and grooves that twist and turn while feeling fantastic.”

Fleck is a 19-time Grammy winner and a genre-blurring banjo virtuoso. From his bluegrass beginnings through his otherworldly Flecktones, his duo with Chick Corea and his reimagining of Rhapsody in Blue, Fleck’s work never fails to surprise.

Harpist Castañeda hails from Bogotá, Colombia, and has led his own bands in addition to sharing projects with such masters as Hiromi, Paquito D’Rivera and Grégoire Maret.

Five-time Grammy-winner Sánchez grew up in Mexico City and built a reputation as one of the great jazz drummers through his work with guitarist Pat Metheny. He has also been a visionary bandleader, helming progressive groups like Bad Hombre, and collaborated with Chick Corea, Gary Burton, Charlie Haden, Michael Brecker and other giants. His Golden Globe–nominated drum-set score for Alejandro González Iñárritu’s 2014 film “Birdman” earned him renown far outside the jazz world.

Doors open at 6:30 p.m. for the 7:30 p.m. show. Tickets are $68 in advance at tinyurl.com/5n93sj98 and $70 at the door. Johnson Hall Opera House is located at 280 Water St. in Gardiner and is handicapped accessible.
