Query: Bacon's tribute to his lifelong friend and others

"Remembering Ansel Adams" (1985) is Bacon's elegy for his friend. Bacon first met Adams in 1927 when both were aspiring concert pianists. And, yes, Ansel played the piano all his life -- he was quite good. Bacon turned toward composing. Adams turned toward photography. Both shared a love of nature and hiked together in the Sierras. They both became environmentalists. Bacon was visiting the Adams home the day Ansel died."Sonata for Cello & Piano" (1948) alternates between somber and lighter moods. At times lively, at times contemplative."Collected Sort Works" (1950-1965)"Tumbleweeds" (1979)
