Rok, I think your criticism and critique of Donald Bird are both accurate and concise. In regard to Pepper Adams and Gerry Mulligan, it's a case of orange or blue.
While both Adams and Mulligan have records I could live without, both have records I wouldn't want to live without. Since you already know about Adams, I'll touch upon Mulligan. On the movie sound track "I Want To Live", he's the primary artist and his brooding baritone sets the mood for the entire movie. This music is also an excellent example of "West Coast Jazz", which I thought was hip at the time, but it came and went. No aficionado's collection is complete without it, if for no more than to know what it is.
I stated "A food critic must sample many dishes before he knows which is best". This critic has sampled many dishes that belonged in the garbage, and that's where I'll leave them. In this stage and phase of our lives as "jazz aficionado's", it's time to focus on the best and forget about the rest, that eliminates tangents like "Sun Ra". Fortunately, "we" meaning those of us who are still posting, are fairly "sympatico" in regard to what's best.
Apparently most of the "aficionados" have gone elsewhere, consequently we're all that's left; therefore, this thread has officially become, "The best of the best and leave the rest".
HAPPY TURKEY DAY TO ALL.
