Favorite boutique labels?

[Stonewall15]

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.

I'd say those are "treasure chest" not "boutique"
