Talk about sound, Boss. Just what kind of Gregorian Chant juxtaposition
(best word I can think of at this ungodly hour) with the clarinet do you
listen to? I simply adore Gregorian Chant and I also am fond of the
clarinet. Combining the two seems a bit off-beat and confusing, but I know
better than to question your tastes. Will you share label(s) with me so I
can also taste and perhaps in a way, delve into your inner sanctum?
Cordially,
