I recall, back in the 1970s, getting regular mailings from Radiola
with descriptions of their new releases.  One was an lp containing
broadcasts of a mid-fifties live concert show, "Rock N' Roll Dance
Party", hosted by dj Alan Freed.  I remember that these supposedly
came from glass based lacquers discovered in Germany.

So were glass-based lacquers still manufactured that late?  Were they
used for disc mastering mostly, rather than providing more common
instantaneous records of broadcasts and performances?
