Hello...
I have found that the vinyl recording does not sound as shrill and tiring as the CD. I have Pampered Menial in both formats.
I was given to understand that Pavlov's Dog used the old Jefferson Airplane as their model for vocals. They do sound eerily similar.
To Jab, search eBay, you will find local and overseas availability of the band's material.
I have just bought their third and final album, the official release from a German seller.
Regards,
Jan
