A small label run by producer Tom Wilson (a good thing). Didn't last long enough, some of the dates that weren't issued by Transition were bought by Lion and issued on Blue Note, now I believe that EMI has the label and has issued Japanese cds and US cds under the Blue Note name.
Every Transition I've heard I've really liked!
I'm not sure but I think this was the original lp cover of the Transition lp. You do have, do you not, the "Donald Byrd" Transition lps two cd Connoisseur set? (This Byrd, the "Byrd Blows on Beacon Hill" and the Doug Watkins Transition lp are all included in the two cd set).
