Name an artist that had a great debut album and a great final album

It will be difficult to beat Bob Dylan last and first album... And he goes on better and better....

I will put Leonard Cohen after Dylan....

It seems poets are more able to win this chase and challenge....

While I am at it, have to mention Guy Clark, certainly would not want to offend Steve Earle. Enjoy the music

The Grateful Dead 

David Crosby

The Great Swedish Singer Jussi Bjorling .

Try his "O Holy Night" , Christmas is near and you will never hear it sung like this .
It’s in his native Swedish which is irrelevant , God speaks it and you know the
words .Shot in Sweden.
