Lara Downes’ album “For Lenny” celebrates the 100th birthday of Leonard Bernstein with a special friends-and-family tribute to the man behind the music. The recording features Bernstein’s aptly-named Anniversaries for Piano, new arrangements of his songs, and world premieres of works dedicated to Bernstein by leading American composers, including Stephen Sondheim, John Corigliano, and Stephen Schwartz. The album is introduced by an essay from acclaimed New Yorker writer Adam Gopnik.
