I mean, the Groove Merchants look great and they often sound great.
As a label, it has a high hit rate in my view in terms of quality. The cover art is often so good that you wonder why they haven't been picked up by the Insta-clout crowd, and the music is in that soul jazz sweet spot such that you would have assumed acid jazz and rare groove fans would be all over them. Leaving aside Kudu, the similar Mainstream label has far less attractive cover art and generally weaker records, but it has a far larger presence.
