In 1965, almost immediately after leaving Beaux Arts, Rabinowitz got a first solo exhibition at Gallery Abel Rambert in Paris.

In 1968, during the anarchic months in Paris, Rabinowitz became a member of the atelier populaire, making posters to support the student movement.

Thereafter Rabinowitz was a founding member of atelier critique, an ever-changing group of artists with a loose, non-hierarchical organization.

By 1975, Rabinowitz's mural paintings had raised the attention of a number of architects, one of whom suggested to realize one in the newly built Renault site in Grand-Couronne.

This part of his artistic accomplishment continues till today, with the highlight to date being "Les Otimistes", a façade sculpture consisting of 15 high columns with 86 "flying persons", realized in Fougères, France (2005–2007).
