Author Duane Tudahl has said, 'The sound of '1999' is the sound of Prince and Peggy McCreary.' An audio engineer at Sunset Sound in Los Angeles, McCreary worked extensively with Prince not only on '1999,' but also on 'Purple Rain' and 'Parade,' plus some of Prince's other projects with the Time and Vanity 6. Andrea Swensson connected with McCreary for a fascinating conversation.
