Stuart Nicholson wrote in the BBC Music magazine of the "Rarum" series: "... selected by the artists themselves, this series is of enormous importance in revealing the breadth of each artist's work, as much for the converted as the unconverted looking for a window into the remarkable ECM catalogue". "Listening to my ECM recordings has been an adventure into some of my most memorable musical past," says Chick Corea, whose anthology features the enormously influential Return to Forever band, the enduring piano/vibes duo with Gary Burton, and the Corea, Miroslav Vitous, Roy Haynes trio, another long-running combination, heard with spontaneous improvisations as well as spirited renditions of Thelonious Monk tunes and standards.
