Founded in 1946, the Lansdowne Symphony Orchestra is one of the oldest community orchestras in the Greater Philadelphia area, celebrating more than 50 years of music-making. Its season runs from October to May, and this year it will present five concerts under the leadership of Irving Ludwig, its music director since 1991. Mr. Ludwig brings to the podium his many years of experience as a violinist with the Philadelphia Orchestra. The concertmaster of the Lansdowne Orchestra is Michael Ludwig, son of the music director, and associate concertmaster of the Philadelphia Orchestra. Although the talented musicians who form the core of the 75 + members of the LSO come from many walks of life, they all share a strong love of music. The repertoire includes orchestral music from the Baroque through contemporary classics, including time-honored favorites and interesting rarities.
