Gordian Knot is a progressive rock/metal band directed by bass guitarist Sean Malone. At times its shifting lineup has included Steve Hackett of Genesis, Bill Bruford of King Crimson and Yes, Ron Jarzombek from Watchtower and Spastic Ink as well as Jim Matheos of Fates Warning, several of Malone's former bandmates from Cynic and John Myung from Dream Theater. The music of Gordian Knot is a highly professional mélange of progressive rock and metal, fusion - instrumental music à la Robert Fripp's Guitar Craft (replacing the clean guitar sound with distorted sounds) and his solo-work (compare Gordian Knot's song "Grace" with Fripp's "Evening Star").
