Have listened just once to all 4 cds.Surely the point is Dylan himself constantly changes the style and delivery of his songs.So why not others.Big Cheeses,Jobbers and upstarts have all had a go. What we get is a mixture of the excellent,the good the bad and the downright ugly.Who cares.There are 72 new versions of the maestro's work to cogitate on,disect and discuss. I'll bet his Bobness is having a quiet chuckle at our expense. The money we have lovingly spent will be lovingly received by Amnesty I guess.The Cause is greater than any debate about the quality. Buy ,listen and it will stir you one way or another.Guaranteed.
