Is the air a bit brisker when you step outside each morning? Are your yard and gutters glutted with curled, twisted, multihued reminders of what the trees spent their spring and summer growing? Bandleader Woody Herman's vocal version of "Early Autumn," a rare 1945 Duke Ellington broadcast of "Autumn Serenade," and singer Mark Murphy's take on "Autumn Nocturne" are just a few of the autumnal offerings on this edition of Afterglow, continuing our long-standing "songs of the season" tradition.
