Besides New York City and Detroit, Laredo performed in Washington, D.C. (Kennedy Center, Library of Congress, 1966 in the White House together with her then-husband Jaime Laredo for President Lyndon B. Johnson), in Boston, Buffalo, Chicago, Cleveland, Houston, Indianapolis, Maryland, Nashville, Philadelphia, San Francisco, Santa Barbara and Toronto, at numerous festivals, among them the "Amadeus Festival/Midsummer Nights Festival" in New Jersey, the "Aspen Music Festival and School" in Aspen, Colorado, the "Bridgehampton Chamber Music Festival" in Bridgehampton, New York, the "Caramoor International Music Festival" in Katonah, New York, the "Eastern Music Festival" in Greensboro, North Carolina, the "Maverick Concerts Festival" in Hurley, New York, the "Spoleto Festival USA" in Charleston, South Carolina, the "Great Lakes Chamber Music Festival" in Detroit, the "Music Mountain Summer Chamber Music Festival" in Falls Village, Connecticut and the "Casals Festival" in San Juan, Puerto Rico. She made tours in the season 1976/1977 to Europe (Netherlands, Germany) and Japan, and 1979 to Japan and Hong Kong. Particularly remarkable was her tour in 1989 to Russia (then RSFSR, Moscow, St. Petersburg Leningrad) and the Ukraine (then USSR, Odessa). For an American to come to Russia to play the music of Russian composers – in the same room of the Moscow Conservatory where Rachmaninoff had played – was an extraordinary undertaking. Laredo enjoyed a very warm welcome by the audience and her concerts were sold out. In the Glinka Museum in Moscow she had the opportunity to see Rachmaninoff's original manuscripts.
