Dortmund Variations is an album by British jazz saxophonist Evan Parker and German pianist Georg Gräwe, which was recorded live in 2010 and released on Nuscope.

[1] The Down Beat review by Bill Meyer states "It never feels like one is hanging back and supporting the other; their playing is nimble and unhesitant, advancing in quick flurries and elaborately articulated phrases that fit together marvelously even though the music is entirely improvised.

"[2] In a review for The New York City Jazz Record, Andrey Henkin commented: "Graewe skitters around the keyboard and Parker is downright sprightly in his attack, short blasts and trills aplenty.

Despite the density of the playing, the tonality is airy and spacious - balladic in spots, in others the musical equivalent of an argument between Oberon and Titania.

"[3] Ken Waxman, writing for Jazz Word, called the album "an exploration of adversarial keyboard and reed techniques," and commented: "the pleasure derived from this duo is in chronicling the parries and thrusts of each participant as Graewe and Parker come to musical understandings.
