The record business is a funny business. There's always the possibility that you'll buy the record and not enjoy it. Who do you go to then? Also, there's no way to hear a lot of this music in advance, to even form an opinion. A good example is the early Stan Getz material on Verve. Long before the recent Getz box was announced, I bought the Lonehill version (packaged under Bob Brookmeyer's name), and found I really enjoyed the music. Then when the Getz box came out, I was struck by how much better the sound quality was, and I bought it. I doubt I would've bought the box if I hadn't first owned the "Brookmeyer" package. I suppose guilt over having bought the Lonehill was a factor in buying the Getz box, but it was only one of the factors.
