Query: PP&M Fans Beware

Those who are familar with PP&M's 1960's recordings will be in for a shock. They sound nothing like they did on those old recordings. You can comment on the choice of fine social conscience songs, the solid instrumental accompaniment, but in the end it is the sound they make vocally that counts. And it is not pleasant. Remember, they made Bob Dylan famous with their moving, beautifully sung rendition of "Blowin In The Wind". It was as much how they sung as what they sung, that drew us to PP&M. No more. It is too painful for me to listen to.
