The French band Catherine Ribeiro + Alpes formed in 1968.
It consisted of singer Catherine Ribeiro and composer Patrice Moullet [fr].
The two used to be in the band Catherine Ribeiro + 2Bis but decided to change the name after their first record.
While their style was mostly folk and psychedelic rock in their first years, they also included elements of avant-garde in their music.
Catherine Ribeiro, known for her chaotic and expressive singing style, often penned their lyrics that addressed political and social issues.
