I don't understand the criticisms by some other reviewers of this album's audio quality. Might they be referring to an earlier release of this album (which has been offered in several formats by a few vendors over the years)? The quality is absolutely outstanding, and the readings by Stephanie Beacham, Colm Meaney, Julian Sands, David Warner, Gabriel Byrne, Roger Rees, Minnie Driver, and Samantha Eggar are as fine as you could ever want.
There are 88 "tracks" on this album. Unfortunately Audible's space limitations preclude me from providing here a Table of Contents. What I will say is that titles of poems are introduced, but not who's narrating what: a typical (and frustrating) lapse in documentation by Audible.
Any Yeats lover should buy this new release, as roughly a quarter of the poems are not present on the 4 other Audible.com Yeats compilations.
Having listened to both Naxos sets (Anton Lesser), Blackstone (Ralph Cosham) and (Nadia May) for some years, I have to say that Griffin really holds the listener. You can soon skip the biography if you wish. You can also enjoy and learn from 'Paradise Regained' as this, too, is really an added bonus in this set!
If you are troubled with understanding at first, read Lanzana's novel or his plain English version. C. S. Lewis has a famous 'Preface'. Nicolson's 'Reader's Guide to John Milton' is also a great way to start. Blarmire's 'Milton's Creation' is a superb commentary.
Keep listening to Milton, especially this set, and you'll find a life-long friend - by far the best writer of all!
