World/era, correct, that it was. But for me, the real "iconic" moments for those had already occurred. For that type of tenor playi9ng, it was Michael Brecker's longasss opening solo on the second side of the first Dreams album (think I heard that in 72 or 73, but jesuschrist was that man playing some kind of youngbloodjazzrock tenor there), and for that type of big band-ish concept, it was Spring of the same year, when Lab '75 was released, the one that was all Lyle Mays. Really an impact there, because Leon Breeden basically handed the full reigns of the band over to Mays for a semester (something it was said has never happened before or since), and since the policy at NT was (and still is) open rehearsals for all bands, it was possible to see/hear that music come togetehr over time. It was unique music by a unique person, and one could be forgiven for thinking for a little bit that it was always going to be like this, that these crazy geniuses were always going to pop up and create a body of idiosyncrtaic hip youngfolkbigband. Of course, it wasn't, but it was fun while it lasted.
Anyway, I still dig "Silver 'N Brass", and that one Berg solo in particualr, all past memories aside. They're just groovy, ya' know? GROOVY!
