Lossy or lossless? Any opinions?

Hi again!
I noticed that you people are really helpful in determining lossiness vs losslessness, so here's another recording that is controversial: Black Sabbath live in Pittsburgh in 1978. It is Pre-FM or SBD. Actually I have two versions of this recording - one claims to be a clone of the master tape, one comes without any lineage info. Both look a bit different, So here I uploading spectral & frequency pics of both, the 'Master clone' and the 'Different version'. Any opinions are welcome!
Thanks and best,
Linda

Thanks for the response! I assume that "post-FM" means: lossy-sourced?

Considering the year this was recorded it's not lossy based. More than likely the equipment used at the time.

Years later, and with further information gathered, I am now fairly sure that this is sourced from the MP3 320K files on Wolfgang's Vault.

It's hard to determine if high quality mp3 like 320 kbps was used

IMO it looks like it was either denoised or from lossy codec.
