As we should all know on this board: Art is subjective. I happen to love Patinkin's concertizing. He is passionate and whether you like what he does or not, you KNOW he is feeling what he is doing. Much prefer that over Feinstein and others who just sort of diddle through their songs.
Of course, I allow for the fact that there are those who LIKE that style too. I don't think you HAVE to like anyone as an artist, but you do have to allow that others may have a different opinion.
Streisand, for example, has a great voice, but she is so technical and self-indulgent in listening to her own great voice that she forgets to imbue the songs she sings with any emotion or passion.
Just my preference.
