Tip. Edition of 500. Pascal Comelade and Richard Pinhas met in Paris in 1974, when Pinhas was beginning to go on stage with his group Heldon. With Heldon and, afterwards, solo, Pinhas became the pioneer and accelerator of electronic music in France, and a fundamental reference throughout the world. Comelade’s electronic period was much shorter, from 1974 to 1981. From 1983 on, he developed his policy of instrumental, strictly acoustic music.

In 1975, Pinhas recorded the introduction to Comelade’s Fluence album. In 1996, Comelade recorded 'Back to schizo' with Pinhas. In 1999, Comelade and Pinhas recorded their first duo album, a CD for the Les disques du soleil et de l’acier label: Oblique Sessions II. In 2012, they released a second CD album for the G3G label in Barcelona, Flip Side of Sophism. In 2018, Comelade again invited Pinhas on his album Le cut-up populaire. 

During the last few years, they have had several concerts as a duo in Paris (Cité de la musique, La Maroquinerie) and Barcelona (Sónar Festival).

They met again in 2020 for this LP album, Le plan de Paris. It contains six titles that were either previously unreleased or completely revisited, developed, remixed.
