Queen's fourth record, "A Night at the Opera," was the one that set them apart from the rest. A rock album unlike any others, with all the various tricks and treats that have become part of the Queen style, is now celebrating it's 50th anniversary.

Author Gillian G. Gaar has written a great new book, filled with fascinating information about the making of the album and brimming with amazing photographs from the era. "Queen & A Night at the Opera- 50 Years" is available right now from Motorbooks.
