Rock is not high-end-ish music.
It's more complicated to record well and therefore it often doesn't sound as good as Jazz or Classical.
Revdog, prog bands even with big contracts such as Jethro Tull havn't been recorded well on the most cases.
Contrary, Can being always an undergrownd band without any mega-million contracts, has excellent recordings (every single one of them), thanks to the Holger Czukay's extra talent of a recording engineer(no extra spendings to producers etc...). The reasons that it couldn't be played in NYC CES are
1)they're unknown to the public
2)they have a lot of sophisticated cacophonic reefs that would only be understandable to an experienced listener or musician.
FZ having some relation to a mix of everything also didn't sound well on many of his albums.
