Thanks. I found some pictures of the smallish studio and what would now be considered recording gear at Motown.
What strikes me is how such a big sound came from those cramped quarters. As you said, with enough overdubbing of the tracks, a lot of audio magic can happen.
Indeed. IIRC I once heard where some of Patti Pages vocals were overdubs of about 16 variations of her own voice.
I bet that’s Tony in the pic. Talked to him many times but never met him.
