Unity Variations is an album by British jazz saxophonist Evan Parker and German pianist Georg Gräwe, which was recorded in 1998 during the Empty Bottle Festival of Jazz and Improvised Music and released on Okka Disk. Before this live performance, they had played in duo just once before at the 1991 October Meeting at the Bimhuis in Amsterdam.[1]
In her review for AllMusic, Joslyn Layne states "This excellent performance showcases the very complementary interaction of the duo, the sort of interaction that often becomes a feat of close listening even while playing without pause."[2]
