Thought for the moment.

I'm listening to AC/DC's Fly on the Wall for the first time in two decades, on vinyl.
There are some great songs and potentially fat chops on this album, but was it spoiled by production decisions?
It has a very "in the room" production, where it genuinely sounds like they're playing in a church hall and you are one of fifty people at the far end, loving it. But it just doesn't work as a reference work.
Like Black Sabbath's output between Vol.4 and Technical Ecstacy, like most rock music between 1978 and the late 90s, no-one seems to be listening to the guys and girls who have been working with mic placement and room mapping.
