Eric Adams has been the singer of the heavy metal band Manowar since 1980. He is known for holding high note screams for over 40 seconds at Manowar shows. About his own artistic influences, Adams declared that as a young man he used to go to every show of Deep Purple's, because he loved Ian Gillan's voice. Afterwards, he worked to create his own, personal style.
A considerable part of Manowar's production implies the intent to optimize and underscore Adams's vocal skills (for instance, the whole album Into Glory Ride (1983), where the singer "makes the difference").
