38. Keith Jarrett Quartet
This eclectic unit, featuring Dewey Redman, Charlie Haden, and Paul Motian, stayed together for five years (1971 to 1976) and was underappreciated for many more. But in recent times, the so-called “American” Quartet’s stock has risen sharply. The adoration expressed for its fearlessly exploratory music by younger players like Branford Marsalis and the Bad Plus certainly hasn’t hurt. On The Survivors’ Suite (ECM), an ambitious two-part work released in 1976, Jarrett—typically for this band—plays not only piano but also soprano sax, bass recorder, celeste, and drums.
