What the hell is Progressive?

[Jeff House <jjthandmeh@juno.com>]

Me:  "After all this Prog talk has got me wondering.  Where do you see The
Who gettting Progressive?  Rael, Relax, Tommy?"

keets: "The Ox."

Clearly I do not understand the Progressive label.  I always thought that
pretension was the single most important characteristic.  Is "The Ox"
progressive because of it is hard and jammy with lots of tempo and melodic
changes?  It is definitely not pretentious.
