The first three records by the French-Portuguese singer Catherine Ribeiro and her inventive, psychedelic backing band Alpes are the types of elusive record-collector gems that feel like transmissions from another world. These new reissues from Anthology Recordings mark their first official release in the United States, and, up until now, their legend was due in part to their scarcity. Kim Gordon, one of Ribeiro’s most vocal supporters, recently noted that she only discovered Alpes’ 1971 sophomore album, Âme Debout, around a decade ago, possibly hipped to it by Jim O’Rourke. A lot of people arrive at Ribeiro’s music with similar stories. You hear this unearthly voice emerging from somebody’s speakers. You listen to the wild, visionary music accompanying it. Suddenly you need to know everything.
