Mercury, Mercury Living Presence
composed by George Gershwin
This performance was recorded live in the Eastman Theater in Rochester New York, May 4,1957. Only three microphones were used - left, center and right - direct to an Ampex 300-3 three-channel 1/2 tape recorder.

Most, probably all Mercury stereo classical titles were recorded in three-channel stereo. The 3-track 35 mm or 3-track half-inch tape stereo masters were edited and the three channels mixed down by means of a special electronic process developed by C. Robert Fine... to make quarter-inch two-channel master tapes, from which most of Mercury’s records and tapes were produced.

Two-track Mercury Living Presence Seeing-Ear Stereophonic Tape Recordings are 1:1 duplicates of a first or second generation copy of the 1/4 2-channel master.

The $12.95 list price is equivalent to nearly $150 in 2024.
