I personally can't tell ya much of anything. I do not work there or anything. I poked my head in for 60 or so minutes which was more than enough to tell me that they have a LOT of great music that I would love to hear. We are talking about a studio (Gold Star/Sugar Hill) that has been in continuous operation since the 1940's.... Not every note committed to tape is findable (or listenable)... A lot of the reels had questionable and cryptic notes attached as to what exactly it was on there and a lot of the work that Alec seemed to be doing was re-splicing decades old splice jobs to be able to find out..... Sometimes things were clearly a band you knew.... Other times not so much (random lounge singers with notes that just read "Fem vox" or some such)....Gotta listen to the whole reel in case there is some gem at the end....
If you are interested, you might enjoy this book.
