Rok, while perusing a "Mosaic" catalog, I discovered something worth considering, "Charles Mingus - The Jazz Workshop Concerts 1964 -65"; this is considered an epic masterpiece. While you may have it in bits and pieces, I don't think I have it. This includes Town Hall, Amsterdam, Monterey 64, Monterey 65, and Minneapolis; 7 CD's $119.
In Mingus's Jazz Workshop the exploration never stopped. Rehearsals could go for days. His music looked back to all the history of jazz. The music ranges from his interpretations of Ellington, to tributes to his musicians, ("Praying With Eric).
The musicians: Jaki Byard, Piano; Johnny Coles, trumpet; Lonnie Hillyer, trumpet; Eric Dolphy, alto, plus bass clarinet and flute; Charles McPherson, alto; and last but not least "Dannie Richmond", drums. A man of style and precision, immaculately dressed, he perfected the art of folding and packing his flawless wardrobe inside a small suitcase. He died in 1988 in a hotel in New York en route to join the Mingus Dynasty band in Europe. He was 56 years old, the same age at which Mingus died.
You probably know more about these particular concerts than I do; do you buy the complete edition for $119, or get bits and pieces for less, that is the question? It depends on whether or not you got $119 as loose change. One thing is for certain, no one got more out of musicians than Mingus, even the one's you weren't too particular about sounded good.
Enjoy the music.
