In 1960 Bernstein and the New York Philharmonic held a Mahler Festival to mark the centenary of the composer's birth. Bernstein, Walter and Mitropoulos conducted performances. The composer's widow, Alma, attended some of Bernstein's rehearsals. In 1960 Bernstein also made his first commercial recording of a Mahler symphony (the Fourth) and over the next seven years he made the first complete cycle of recordings of all nine of Mahler's completed symphonies. (All featured the New York Philharmonic except the 8th Symphony which was recorded with the London Symphony Orchestra following a concert in the Royal Albert Hall in London in 1966.) The success of these recordings, along with Bernstein's concert performances and television talks, was an important, if not vital, part of the revival of interest in Mahler in the 1960s, especially in the U.S. Bernstein claimed that he identified with the works on a personal level, and once said of the composer: " showered a rain of beauty on this world that has not been equaled since".
