The LaSalle Quartet was best known for its espousal of the Second Viennese School of Schoenberg, Berg and Webern, and of the European modernists who derived from that tradition, though they also performed standard classical and romantic literature. The Quartet gave the premiere of Witold Lutosławski's String Quartet in Stockholm in 1965. György Ligeti dedicated his Second String Quartet to the group, and they premiered it in Baden-Baden on December 14, 1969. The quartet has been credited with the "Zemlinsky Renaissance," as Zemlinsky remained largely unknown until they performed his works. The quartet won the Deutscher Schallplattenpreis for their recording of his four string quartets.
