If there were ever any doubts as to Ralph Towner’s consummate abilities, though one would need to travel far to encounter them, they can only have been put to rest with the release of Blue Sun. A near highpoint in Towner’s extensive discography, it might have shared the summit of 1980’s Solo Concert were it not for a few frayed threads. Towner’s compositions are already so harmonically dense in their solo form that other instruments merely externalize what is already so internally apparent to them, so that the intimate pickings of “The Prince And The Sage,” “Mevlana Etude,” and “Wedding Of The Streams” hover most clearly before our ears. At the same time, there is something skeletal about his playing that cries for flesh. Not for want of completeness, nor out of lack, but rather through the his balance and inward posture, a flower-like duplicity that embraces both blooming and wilting in the same breath.
