Ken, as long as you know what you like, that's all that counts.
"Winter Moon" even sounds like Art Pepper, dark and brooding. Although I never met the man or saw him live, I felt that I knew him, that's because of his very revealing autobiography.
It's easy to see how you could get so absorbed in Art Pepper; I've been into jazz all my life, and this is a first for me in regard to this side of Art Pepper. This proves a person doesn't have to go to the latest music in order to find something new.
Enjoy the music.
