She was noted for her strong commitment to chamber music and said that soloists particularly need this experience as a preparation for concerts with big orchestras. “The lack of it is evident when a soloist performs as if the orchestra were a mere accompaniment,” Laredo said. She collaborated frequently with the Shanghai Quartet (regularly at the Music Mountain Festival), and among others with the American, Budapest, Emerson, Manhattan, Muir, St. Lawrence, St. Petersburg, Veronika and the Vermeer Quartet, with the Chappaqua, Manhattan Chamber, Orpheus Chamber and Saint Paul Chamber Orchestra, with the Philharmonia Virtuosi, the Sea Cliff Chamber Players and the Orchestra of St. Luke's. She appeared with the Guarneri Quartet and the Tokyo String Quartet in the Lincoln Center series "Great Performers". She helped the Tokyo String Quartet several times when a member of the Quartet was indisposed transforming the group temporarily into a piano quartet. Since their first association in 1980 in Alice Tully Hall, she toured each season with the flutist Paula Robison as the “Paula and Ruth” duo.
