Mentioned on the famous Nurse With Wound list, the path followed by Jean Cohen-Solal included many exciting adventures in the 1970s, from his participation in the cult animation series Les Shadoks where his voice can be heard alongside the actor Claude Piéplu, to his proximity to the GRM where he worked alongside Bernard Parmegiani, François Bayle, Luc Ferrari, Guy Reibel and Béatrice Ferreyra, or his involvement in progressive music with Captain Tarthopom (1973), an album very much in the same style as that featured in Europe on the Vertigo label, but in an instrumental form, and even more audacious, without turning its back on the same classical influences as everyone else."
