Aubry ?Big Juice? Delaine, Nicki Minaj's sound engineer, sat down with Rolling Stone to discuss Minaj's new album 'Queen.' Delaine has served as Minaj?s go-to recording engineer since 2014?s The Pinkprint; and tells Rolling Stone of Nicki's worth ethic. He says, She will meticulously go in and change every little thing; even during the mixing process. That attention to the detail is why she?s the best. I?ve never worked with an artist who paid that level of attention.
