Mysteries: The Impulse Years 1975-1976
Mysteries: The Impulse Years 1975-1976 is a 4CD collection of the Keith Jarrett albums Mysteries, Shades, Byablue and Bop-Be. The set was released in 1996 by Universal Music Group. Previously unreleased alternate takes are present on each disc.
The music was performed by Jarrett and his affectionately-titled 'American Quartet', composed of Charlie Haden, Paul Motian, and Dewey Redman. Guilherme Franco contributed additional percussion to Mysteries and Shades.
In 1997, a 5-CD boxset called The Impulse Years: 1973-1974 was also released, composed of Fort Yawuh, Treasure Island, Death and The Flower, and Back Hand.
Aside from their appearances in boxset, Shades and Bop-Be have only ever been released on CD in Japan. However, in October 2011 Shades was reissued internationally (with Mysteries, as a single disc set) as part of the Impulse! 2-on-1 series.
