Ganryu Island is an collaborative album by John Zorn and Michihiro Sato.

[2] The album is titled after Ganryujima, a small island in the Strait of Shimonoseki where legendary samurai warriors Miyamoto Musashi and Sasaki Kojiro engaged in battle.

The AllMusic review by Joslyn Layne stated: "The great, no-holds-barred improvisation is by no means an inchoate whirl -- indeed, the shamisen's rhythmic presence often provides a steady, but flexible structure for the duo's truly imaginative interaction".

[3] The Penguin Guide to Jazz observed that "listening to Ganryu Island is like panning for gold: seeming eternities spent lodging through muddy dross in order to turn up a few moments of pure gold.

By the oddest perversity, the very best tracks seem to be those which were excluded from the venial release".
