It may seem like Leslie Feist was an overnight sensation, but her way too success was paved with an impressive number of collaborations. She played guitar in By Divine Right, provided stellar contributions to the Toronto collective Broken Social Scene, wrote songs for others, sang backup, duetted, and soundtracked. Her lifelong friendship with two of Canada's most famous expats—Gonzales and Peaches—led to numerous collaborations with French singers, Canadian rockers, Norwegian producers, American comedians, and even famous puppets. That girl has not only seen it all—she's done it all.
