- frank zappa & the mothers of invention: bacon fat - live at the rockpile '69
(2017, cd, uk, keyhole)
I'm not trying to promote these semi-official releases, but I do admit that some of these look nice and sound even better.
This "Bacon Fat" release (taken from the 1969/02/23 Toronto concert) is such an album.
So go to Zappateers and download the show for free.
