OK, found their web site
http://www.cherryred.co.uk/esoteric/index.htm.
So they are affiliated with "Cherry Red", well that provides good reason for quality of their reissues.
AND, I just realized they compiled and released the Jack Bruce boxset, so far my vote as best boxset of the year.
Here's an announcement found on their Web site.
Welcome to Esoteric Recordings, the home of good music. Established in 2007 and label managed by Mark Powell, Esoteric Recordings is the home of good music, with all releases finely packaged and remastered from the best possible sources to ensure the highest possible audio quality.

Nice video on website talking about the creation of the label! (I wonder if they are hiring,) :}
