Paul O'Neill (February 23, 1956 – April 5, 2017) was an American music composer, lyricist, producer, and songwriter.
Among other bands, O'Neill helmed Aerosmith’s Classics Live I and Classics Live II albums before beginning a fortuitous relationship with the band Savatage that led to conceptual pieces such as Hall of the Mountain King, Gutter Ballet, Streets: A Rock Opera and Dead Winter Dead. It also introduced him to Jon Oliva, Bob Kinkel and Al Pitrelli, as well as reconnecting him with studio engineer Dave Wittman, who all became original collaborators in O'Neill’s next group, Trans-Siberian Orchestra.
He sadly passed away on April 5, 2017 from an unexpected reaction to prescribed medications to treat his numerous chronic illnesses (including bone augmentation surgery, complications from spinal fusion surgery, heart disease, and hypertension).
