I'm late on this one as well. Thanks to Tony, I can contribute.
This is excellent material. (The entire Vanguard Showcase series I believe is superb, all those that I have heard share a recording excellence and a musical vision that pleases me very much).
Vic plays so darned well here. It's almost as if he has the history of jazz trombone in the bell of his horn and places notes from that history right where they should be. His sound and phrasing are ironically all his own however, and there is a large sense of "personality" in his playing that really comes through to me --- I'm one of those who feels that master musicians reveal their personality in their music, that has been a controversial concept on this board before, but I'm on this side of that debate.
I really like Ed Hall's work on these sessions and also Braff and Collins. And the rhythm section. . . well it is almost as if the classic Basie "Rheno Club" swinging rhythm sound is the "gold standard" for this entire series: no matter who is really in the section, that Basie quartet swing sound is the reference point, and each time it is well and convincingly done. (Sir Charles Thompson really pulls off the the Basie hat with ease!) Swing, swing, swing. Walter Page is probably very responsible reprising his role, but on the other releases this Basiesque beat and feel are equally successfully invoked.
Just great music that gets into your mind and heart and makes you feel good. This is a prime example of a type of jazz that makes me a jazz fanatic. I want (and I guess NEED) the warmth and hope that I get from hearing jazz like this. Thanks Vic! (And thanks Tony! Great choice!)
