Edwin Franko Goldman was an American composer and conductor. One of the most significant American band composers of the early 20th century, Goldman composed over 150 works, but is best known for his marches. He founded the renowned Goldman Band of New York City and the American Bandmasters Association. I’ve seen several other books he co-wrote sell for $200 or more.
