Producer Tony Berg began his career during the late 1970s as a session guitarist, often playing on soft-rock releases from performers including Air Supply (1977's Love and Other Bruises) and Debby Boone (1979's Midstream). After racking up any number of studio credits not only as an instrumentalist but also as an arranger, he moved into production during the late 1980s, scoring his first major success with Michael Penn's 1989 debut March. By 1990 Berg was among the most prolific producers in the business, that year alone working on Wendy Lisa's Eroica, Edie Brickell's Ghost of a Dog and Public Image Limited's The Greatest Hits, So Far. In 1991, he continued his frenetic pace with Squeeze's Play and Animal Logic's Rose Colored Glasses. Lacking a clearly defined signature sound, Berg's trademark was instead his sheer eclecticism -- in 1993, for example, he produced diverse efforts ranging from X's Hey Zeus! to Bruce Hornsby's Harbor Lights to Aimee Mann's Whatever. In addition to production duties, he later also served as an A&R exec with the Geffen label. ~ Jason Ankeny, Rovi
