Time for Three mixes classical, country-western, gypsy, bluegrass, and jazz music to create a unique hybrid sound. Violinists Zachary De Pue and Nicholas Kendall and double bassist Ranaan Mayer met while studying music in college. The three-piece bonded over a shared love of musical improvisation and went on to play more than 200 shows. Conductor Christopher Confessore leads the trio with a skillful eye and even more skillful conductor’s wand. Though the concert begins at 8 p.m., it’s preceded by a cocktail hour that begins at 7 p.m., where guests can impress each other by playing octave-jumping leapfrog.
