Query: Some stunning lesser known american pieces

The standouts are the Harris organ and brass piece, available nowhere else that I know of. Organic development of motifs to a massive climax. The two Ives pieces are also firstrate. "From the steeples to the mountains" lives up to Ives' description: And then the rocks began to shout. "Let there be light" sounds as though it could have led to his parting ways with the church he was organist for in the early 1900s.The other pieces are pretty minor. The Carl Ruggles piece is interesting.
