Pianist Tom Montgomery first came upon the music of the tango through the great Argentine composer Astor Piazzolla. Trained as a classical and jazz musician, Montgomery’s passion for tango has become a central focus of his work for more than a decade. This passion led him to the bandoneon, an accordion-like instrument essential to the tango, and to the formation of his own dance ensemble, Montango. Now considered one of the Bay Area’s premier tango groups, Montango has performed the world over, sharing their passion for the cultural treasure. This week, Tom Montgomery and Montango dazzle the North Bay when they perform on Saturday, Sept. 6, at the White Barn, 2727 Sulphur Springs Ave., St. Helena. 6:30pm. $30. 707.251.8715.
