This is one of the best of Birds later recordings !
Now listening: June Tyson ! I love her voice, I love the lyrics and Sun Ra was one of my favourites from the very beginning, when I started to listen to afro american music ! Sun Ra, Ornette, late Trane, Pharoah Sanders, electric Miles, and ....Mingus.....those where my favourites in my early teens.
I saw the Arkestra with June Tyson of course and was deeply moved by her angelic voice, the "Space Songs and Chants", wonderful.
And as a generation thing: Sure I got acquainted first to the kind of music that was played then in the early 70´s, and it was the Arkestra, where I first heard some old jazz too, those Fletcher Henderson things. I had never heard about that before and loved it, I believed it´s a special "Space Jump", had no idea that this was the jazz of earlier decades of the century....
Same with Mingus....heard the pianists do some stride sections at one point and heard that kind of old thing for the first time.
