Mike Pasternak, better known by his stage name of Emperor Rosko (born December 26, 1942) is a well known pop radio presenter.

Born Michael Joseph Pasternak, he is the son of Hollywood film producer Joe Pasternak. He was influenced in his career choice by KYA Radio Los Angeles DJs Emperor Hudson and Wolfman Jack. Rosko’s opportunity to broadcast came whilst in the US Navy where he presented a show on an aircraft carrier. He then went to Europe and hosted sponsored programmes in France and Belgium.

He joined Radio Caroline, a pirate radio station broadcasting from a ship off the coast of England, in 1964. There, his pacey American style soon made Rosko one of the station’s best loved DJs. He then was heard on French language stations Radio Monte Carlo and Radio Luxembourg.

It is Rosko who is heard introducing soul singer Otis Redding, as well as encouraging the crowd to chant and spell his name on Redding’s album Live in Europe, recorded on March 17 and March 21, 1967.
