I'm pretty sure this copy is as stated, MSR > R > D > CD, but if there's a digital master circulating that's beside the point. This copy didn't come recetnly into circulation; it came out of an old collection into our hands a few years ago.
It would still be nice if we can turn up a decent AUD of Scarlet Begonias but that sounds less promising from what we're hearing. And if a digital master already circulates may that's that. I wouldn't claim this is the best show of the year but I found plenty to enjoy listening through it last night. The jam out of Eyes is delicious & exceptional, To Lay Me Down is exception even for '74, and the entire last hour of jamming is strictly no complaints.
