HomeMusicReview: Gordian Knot Gordian Knot “Emergent” (Sensory) Bill Bruford gives the thunderous bottom end of some righteous percussion to this seven-member post-fusion prog rock group. Bruford is one of the core members of this group, and guests round out an array seven. One of those guests is Genesis guitarist Steve Hackett. The sound is fleshed out in the studio by co-producer Scott Burns, known for getting the big, angry sound for extreme metal. Leading the group in their instrumental forays is bass stick maestro Sean Malone. Some of the keyboard episodes get rather pretentious, but overall this is a solid record of both artistry and proficiency.
