On a gerneral note, and after finishing Powell's biography, I have the impression that Puente often wanted too much at a time. He suffered from the snobbishness of most Cubans towards Puerto Ricans and wanted to be better in all respects. He was a studied musician with great arranging skills taking jazz as his yardstick, which was perfect for what we call Latin Jazz, but perhaps overloaded the whole thing. It would be interesting to hear how his band sounded on a live gig in the 1950's, without the three minute time limitation of a 78 rpm record, which he seemingly internalized to a high degree; this may have been supported by his producers who wanted selling singles and radio play. For the dancing audience of later days his music was too sophisticated. Until his death he dreamed of some very ambitious projects with orchestras and all that never were done the way he really wanted. It was a question of financing projects, just as well. You get a good glance at his personality from Powells's book, she was very close to him.
His music often is truly eciting, but never moves me as much as e.g. Mongo's band, who had more warmth and good spirits. Puente is like the Kenton of Latin Jazz.
Right now I am waiting for a copy of the RCA box Vol. 2 to arrive which was shipped from Israel and might take a few weeks to arrive here. This will give me some more insight into the chronology of recordings dates, I hope.
TTK, do you know of any live recordings of Puente before 1960?
