Biography
Composer/pianist George Russell gathered together a very versatile group of talents (trumpeter Don Ellis, trombonist Dave Baker, Eric Dolphy on alto and bass clarinet, bassist Steve Swallow, drummer Joe Hunt, tenor saxophonist Dave Young, ...).
The music is post-bop and although using ideas from avant-garde jazz, it does not fall into any simple category.
