To address the OP original post and point… Early recording had way less BS in between the performance and the Recording engineers. Also all of the recordings were ANALOG, and TUBES… Some recordings were almost Direct to Disc with very little processing since it didn’t exist. The original RCA shaded dogs, and Mercury’s from the 50’s sound to die for… Many are available as DSD down loads from HD Tracks or Acoustic Sounds. Lots of early to mid-ish 60’s recordings are also amazing in there naturalness … The Doors, Beatles, Joni Mitchell, Simon and Garfunkel; all these where recorded on Analog tape with most using Tube amps and mics.
