Les Double Six (also known as the Double Six of Paris) was a French vocal jazz group established in 1959 by Mimi Perrin. The group established an international reputation in the early 1960s. The name of the group was an allusion to the fact that the sextet used double-tracking techniques to enhance and 'fatten' the sound, very much like Brian Wilson of the Beach Boys did in the recording studio. The membership of the group varied from recording to recording. The six members would all sing once to a recording track, then sing the exact duplicate performance again to a second track, "doubling" each individual vocal part.
