Query: A hard to find classic.

Here is a near impossible to fine CD. Very limited in production, available only from Japan and very expensive. The tracks are typical Wakeman greatness. The Birdman of Alcatraz is a stunning piece of work. Chambers of Horrors shows Rick's creativity especially in the ending scream. There is a funny story about it. All in all, a must for the Wakeman devotees. Good luck tracking one down.
