The Hissing of Summer Lawns is the seventh studio album by the Canadian singer-songwriter Joni Mitchell, released in November 1975 on Asylum Records. It continues the jazz-influenced sound of Mitchell's previous album, Court and Spark, with more unconventional and experimental material. It features synthesizers such as the Moog and ARP, sampling, backing from the jazz-rock groups the L.A. Express and the Jazz Crusaders, and contributions from James Taylor, David Crosby, and Graham Nash.
