Joni Mitchell - The Hissing Of Summer Lawns (1975) LP

Joni Mitchell evolved from the smooth jazz-pop of Court and Spark to the radical Hissing of Summer Lawns, an adventurous work that remains among her most difficult records. After opening with the graceful "In France They Kiss on Main Street," the album veers sharply into "The Jungle Line," an odd, Moog-driven piece backed by the rhythms of the warrior drums of Burundi — a move into multiculturalism that beat the likes of Paul Simon, Peter Gabriel, and Sting to the punch by a decade. While not as prescient, songs like "Edith and the Kingpin" and "Harry's House — Centerpiece" are no less complex or idiosyncratic, employing minor-key melodies and richly detailed lyrics to arrive at a strange and beautiful fusion of jazz and shimmering avant pop.
