This is a now dated, but still very readable book by Eugene Burger. He looks at the question brought about the appearance of the tuxedo-clad magician and the meaning of what is magic that is not readily apparent.

Burger's definition of bizarre magic ( the antithesis of conventional magic ) is somewhat narrow as it looks as if he was influenced by his friendship with Tony Andruzzi, who is often marked as the champion of bizarre magic. His overview of unconventional magicians include Penn & Teller, Max Maven, etc.
