Official BYG album Newly remastered Deluxe Vinyl Edition Comes in deluxe gatefold sleeve with exclusive artwork. A true milestone of French underground music, Catalyse by Ame Son returns in its fullest-ever vinyl edition, newly expanded with bonus improvisations never included on the original pressing. First released in 1970 on the avant-garde BYG label, Catalyse is widely considered the first psychedelic rock album made in France-a vibrant, adventurous fusion of English psychedelia, French poetry, free jazz, and experimentalism. Founded by ex-Banana Moon members Marc Blanc (vocals, drums) and Patrick Fontaine (bass), Ame Son crafted a sound that drew comparisons to Gong and Soft Machine, yet remained distinctly their own.

The album’s concept was to create multi-part compositions forming a continuously evolving suite, rich with shifting atmospheres and improvisational passages. This expanded edition, fully restored and remastered from the original master tapes, also includes the group’s debut single “Je Veux Juste Dire” / “Unity,” making it an essential document for collectors and fans of psychedelic, progressive, and experimental rock.

Long out of print and highly sought after, Catalyse is now available again-restored, expanded, and ready to inspire a new generation with its boundary-pushing vision and energy
