(and, BTW, a good critic can easily have a personal dislike of the artist but find his or her work superb. Van Morrison can be an arsehole at times, but I hugely respect some of his earlier stuff. Ditto many others. There have been many threads on this forum over the years expressing astonishment at the personal problems of some musicians compared to the sublime stuff they produce. It's what objective criticism involves - the separation of the performer from the performed. Of course, it can put one in a tricky position; I've not yet heard any of David Hannam's work or Nick Griffin's...)
