Haden, what a master. I'm not always crazy about his work, but he has been an important part of many sessions and MADE them, and that includes pop sessions as well as jazz (or odd permutations thereof, thinking in particular of contributions to Rickie Lee Jones' recordings.)
He has amazing command of the instrument, open open open ears, and is so amazingly cooperative with other musicians. (He does not domineer as some others may do.) And that tone!
I have many favorite bassists, and I would also probably forget to list him in a list of my favorites, but he is well-represented in my collection, and there are so many instances where I go "Wow Charlie!" in playback. . . .
