Well, I can tell you already, not having received these new copies, that the sessions themselves are fantastic. The Murray is well-recorded and compositionally interesting, held together a lot more than the BYG records of the same era. This was a "working" band and it shows. The quintet track with Alan Silva and Becky Friend (fl) is amazing. Solidarity Unit is an early BAG record, but the open spaces and "textural" use of little instruments is filled in and any "opening up" is in a very raw (like a wound) sort of way. Richard Martin's guitar skitters over the top of the proceedings like a hypercharged, bluesier Ray Russell or some such. So there you go!
Michael King of Reel Recordings fame has remastered them and they're pressed on heavy, quiet vinyl so I assume the reissues will sound a bit better than the OG copies, neither of which were pressed to today's SAWANO-style standards.
