Tom Varner turned heads and opened eyes on the jazz scene in the early '80s. There weren't, and still aren't, many French horn players who improvise and play with the facility he demonstrated on this 1980 session. There were five tracks, two of them over 10 minutes, and Varner displayed impressive speed and fire, playing with distinction while matching alto saxophonist Ed Jackson in range, control through every register, phrasing, and tonal quality.
