The Who / Live at the Isle of Wight Festival 1970:  This is a wonderful performance by The Who.  It may not be perfect but let's see You keep it together in front of the largest crowd in history...only to discover that the crowd is in a rowdy mood.  The Who's performance is enjoyable throughout and so this concert is certainly worth owning.  It is an imperfect treasure but a treasure nonetheless.  I love it, so I give it five stars.
