"Rare & Lost Tapes" is a compilation of singles by the renowned band Cortex that were never put on an album. This album collects previously unpublished and rare songs such as "Les Oiseaux Morts" (Alternative Take 76), which was only available as a test pressing, "Mary & Jeff" (Fender Rhodes Version 77) recorded for TV, and "Californie" & "Stevie" issued for the Side Project Caribou as 7". This iconic set by Cortex is a classic example of jazzy funky fusion from the French scene of the 1970s, with a laidback groove that's wonderfully soulful, and which ties them a bit more strongly to American jazz funk that was rising up at the time.
