JackDupon is a French progressive rock band.

The band’s music is created in a “scientific-empirical” way, based on themes, using counter melodies and poly-rhythms performed by one or several of the musicians, and with total improvisations during live performances or recorded and reworked in the studio.

They are often labeled by the media as the worthy heirs of Frank Zappa,[1][2][3] King Crimson[4] and Gong.[5]

Onstage JackDupon, a fictionalized character, travels back and forth through time to help in bettering the world.
