I was thinking the other day about this while talking to a friend about Rod Stewart, who went from fronting the Faces to disco and now this awful, pandering "American Songbook" garbage. But is he really the worst offender? After all, the Faces were playing the style of music that was popular at the time, so it's not too surprising that Stewart followed the trends of popularity, even if it led him to record garbage like "Love Touch." So, what band or artist has had the biggest shift from radical or innovative to pandering and popular? I'm not a fan of Genesis in any of their incarnations, but they seem to me to have had the biggest shift.
