It was a thread in which the subject was pitch and the engineers began to bitch.
One complained about how out of tune Frank Sinatra sang.
I'm like, WTF?

Too bad they can't go back in time and auto tune his vox -- he might have sold some records

I mean, unless they are referring to a couple of really short duration notes that were out by a cent or two, I have no clue. The rest of the planet managed to not notice. If Frankie's vocals aren't good enough, the rest of us should probably hang it the fuck up.
What made me recall that was a recent discussion, on Mixerman's or Kenny's FB page discussing incongruences in mixes. I mentioned Jethro Tull's Aqualung, how the piano was equally as loud as the guitar through a Marshall plexi (or whatever).
Someone then proclaimed it to be an awful sounding album, someone else agrees and again, I'm WTF?

I hadn't listened to the album for a while and I went to listen to the CD at my older brother's place. He has a sick sound system with Bryston amp, Theil speakers, JL subs and a California Audio Labs CD player -- it reveals detail that standard consumer gear won't.
I guess I'm still one of the millions of fools who have been gulled into thinking it's a great sounding album

The only thing I noticed that I though was unusual was at the end of the album there was tape/ console/ outboard noise that virtually nobody would have ever heard on their 1971 stereo which I think they could have gated out for the few people listening to it at 90dB on multi thousand dollar stereos.
