Trey Gunn teams up with extreme drummer, Marco Minnemann, for this tour de force of compositions. Modulator is the culmination of working with a live 50 minute drum solo of Minnemann's. Gunn calls this ''the most challenging recording I have ever taken on.'' All the music was composed and produced on the top of this one contiguous drum solo. ''Considering I don't even care for drum soloing, that these pieces have turned out so amazing, is utterly astounding to me,'' Gunn recounts. Touch guitars, basses, ouds, fiddle, wurlitzers, strings and uillean pipes all make an appearance here. These recording prove, without a doubt, the old saying - ''with great restrictions come great creative leaps.''
