The two most popular artists to record for Britain's Rephlex label -- label-founder Richard D.

James (Aphex Twin) and Michael Paradinas (µ-Ziq) -- collaborated in 1996 for Expert Knob Twiddlers.

Recalling the great Milton Bradley game boxes of the 1970s and '80s, the cover is a picture of James and Paradinas, in suitable low-res, chop-and-paste photos, playing a variant of Connect Four.

Inside, the two techno auteurs' music mesh quite well; Paradinas' liquidy funk distortion smoothes out the calculated, almost sterile, experimentation of Aphex Twin.

The style-blending, however, cancels out the particular attractions of both artists, and the listener is left with a somewhat bland album.

Fans of Aphex and µ-Ziq will be excited, but newcomers should go elsewhere before they dig this deep.
