Le Resevoir, Paris, France. The term "jam-session" was coined in the 1920s when black and white musicians gathered in smoke-filled bars after their respective concerts to enjoy the kind of jazz they could not play in traditional sets. Bing Crosby was a regular at these sessions, and had fun marking the first and third beats of musical phrases by clapping hands, which the musicians call "jammin' the beat". Today, the Seine Sessions revive the happy years of "jam sessions", while the cream of jazz, blues, gipsy and funk Parisian scenes occurs on the boards of the legendary restaurant and jazz club Le RĂŠservoir. Titled "Legendary Jazz", this episode hosted by Eddy King features unique performances by artists playing together for the first time, and interviews with Steve McCraven, Oona Guino, Rodolphe Lauretta, and many others.
