My thoughts as well about Burton's text.
Reminds me of his approach on his tribute disc.
Let me say that this puts Tjader's "Jazz" side into focus, less the Latin Jazz side. That's the way he saw himself, and the way he structured his performances, a set or two of jazz, with the conga player entering the stage for the second or third set.
Have listened to all of disc one now, and Tjader's solos were excellent! Judging by these recordings he was up to par with Bags.
