The Magician's Birthday is the fifth album released by British rock band Uriah Heep. The story line is "based loosely on a short story" written by Ken Hensley in June and July 1972.
Even though it was recorded mere months after the preceding Demons and Wizards, the album features a notably different sound than the band's previous albums, with the aggressive hard rock toned down in favor of a cleaner appearance with more progressive elements, something which had only been hinted previously. This change in sound would define Uriah Heep's following outputs for roughly a decade.
The original vinyl release was a gatefold sleeve, the front of which was designed by Roger Dean. The innerfold had pictures of the band, with the LP itself housed in a liner on which were printed the lyrics.
