BOTTOM LINE: Acoustic, yes, but ear candy, no. Brian Kopper"s "In Absolute Motion" is an entrancing tapestry of music that reels and rocks, floating aimlessly at times and soaring to incredible highs. A beautiful recording. When Missoula musician Brian Kopper set out to make his second CD, he sought something vastly different from his first solo fingerstyle guitar album - something with enough "space" to allow other musicians to shine through. The recently released CD, In Absolute Motion, realizes that goal in a big way, drawing upon the talents not only of Kopper, but several other Montana musicians. The result is an eclectic mix of folk, jazz and world music that defies verbal description.
