World-class violist Dorian Rence, who has performed with the New York Philharmonic for 40 years, has devoted her life to playing music, but she’s just as passionately committed to caring for a small colony of feral cats in the railroad tunnels of New York City. Born in Oklahoma to a father who was both a farmer and a clarinet player, Dorian started piano lessons at the age of 5 before moving to the violin and, eventually, the viola. After studying at the prestigious Curtis Institute of Music, she won her audition with the New York Philharmonic at the young age of 21. Only the seventh woman to become a member of the New York Philharmonic, Dorian has played with a vast array of famed conductors and soloists, including Leonard Bernstein, Pierre Boulez, Zubin Mehta, Luciano Pavarotti, Isaac Stern, and Yo Yo Ma. Deftly incorporating vividly told stories of her life, career, and cats, and featuring several gorgeous performances by Dorian and her musical colleagues, this moving documentary tracks the violist as she goes about her selfless work as a caretaker of ferals, feeding and ultimately rescuing the elderly cats in her colony during a particularly brutal New York winter.
