Which New Year's Eve concert has been performed by the Vienna Philharmonic every January 1 since 1941?

The concert performed by the Vienna Philharmonic every January 1 since 1941 is the Vienna New Year's Concert.

The Vienna New Year's Concert is held in the Musikverein's Golden Hall and focuses mainly on music by the Strauss family and related composers. Its cheerful waltzes, polkas, and marches have made it one of the world's best-known classical music broadcasts. The program traditionally concludes with the “Blue Danube” waltz and the “Radetzky March,” though the exact order and encore details can vary.

The concert's history began during the Second World War, when the Vienna Philharmonic presented the first concert on January 1, 1941. Clemens Krauss was the founding conductor, and the event became an annual New Year's tradition after the war.

It is often called simply the Vienna Philharmonic New Year's Concert. The January 1 performance should not be confused with the orchestra's separate New Year's Eve concert, which is a different event and program.
