OK I can relate - I had that same feeling on hearing it for the first couple of times. And one has to like the voice. If that doesn’t work, it doesn’t quite gel, in other words.
Yea, much of the stuff she gave me was stuff done by himself without any backup... some were just parts of solos, stopping/starting and so on. I would probably sound better if taken into a studio and properly edited and adding other tracks and stuff to it. I didn't want to hurt Barbara's feelings so I pretended to love it all.
