... this record is in HP's Super Disc List for ages.
It was mastered by Bob Ludwig at Sterling Sound, NY in 1974:
look at RL and STERLING in the dead wax.

PS:
I forgot to mention that the accolades for the recording goes to Marc Aubert and Joanna Nickrenz.
It was made with two microphones, careful control of ambient sound, and no gimmicks -
like Mercury used to record the Eastman Wind Ensemble.
It was cut without equalization or limiting, direct from tape to cutter head.
