I am not sure if the Los Angeles Jazz Institute (LAJI) CDs can be considered to be on a boutique label. The were issued in a limited quantity to members only and contained many unreleased sessions of West Coast jazz. The LAJI also released two box sets. In any case these CDs were West Coast jazz at its best.
when I was about 39, I once met Mr Fleischhammer at a record fair... somewhere in a corner, he'd hidden the box with all his CDs, including that Brew Moore incredibly cheap, memory says 3 Euro... I bought quite a few of those CDs and said something like "why do you price them like this?" because I would have thought, there's no good reason to go below 5 or 6... the number of additional buyers you gain by reducing the price of an amazing Brew Moore cd from, say, 5 to 3 must be negligible... the ones who know, know, they may not be large in number, but... and he said something like "I wasn't even sure that whether it made sense to bring CDs to an LP-centric fair like this one"... I must have looked at him, like he came from the moon [which was probably not fair]... I am sure selling the stuff is not as much fun as it should be given the quality... but I don't quite trust his skills in assessing the market...
the people who are now buying all those tonepoets are not from the "corresponding generation"
