Amazon.comThrak finds the quartet responsible for Discipline, Three of a Perfect Pair, and Beat in the '80s reassembled, with Trey Gunn on stick (a basslike instrument) and Pat Mastelotto on percussion joining original members Robert Fripp, Adrian Belew, Tony Levin, and Bill Bruford. Thrak is musically quite similar to the King Crimson albums of the '80s, but it has less of a tribal, rhythmic focus, giving the bulk of the space to the stringed instruments. Bruford and Mastoletto are present and active (check out "B'Boom") but seem to play more of a supporting role. Belew, back from his somewhat successful solo career, resumed his dominant position, providing all the vocals and plenty of his distinctive backward-sounding guitar work. --Adem Tepedelen
