The extravagant Fasig-Tipton Pavilion houses this year’s Chamber Music Festival of Lexington, where acclaimed musicians give majestic performances and host master classes. Friday evening reveals a nuanced rendition of Dvořák's Terzetto in C Major, as delivered in part by the festival's artistic director, Nathan Cole, who also holds the position of first associate concertmaster with the Los Angeles Philharmonic. Ravel's Trio in A Minor brings together soothing sounds of piano, violin, and cello, ad Schubert's famed Trout Quintet dances between strings, piano, and a trio of opera-singing fish. Saturday evening ushers in Busoni's Sonata no. 2 in E—its ivory, dulcet piano tickled by Alessio Bax, who has appeared as a soloist with more than 85 orchestras worldwide. Bach's Sheep May Safely Graze and a world premiere written by Daniel Kellogg set the sound stage for Dvořák's Quintet in G Major, as two violins, a viola, a cello, and a double bass come together to fight musical crimes wrought by vuvuzelas and Christmas recordings of dogs barking.
