Writing about Cher's musical output during the 1960s, Robert Hilburn of the "Los Angeles Times" stated that "Rock was subsequently blessed with the staggering blues exclamations of Janis Joplin in the late '60s and the raw poetic force of Patti Smith in the mid-'70s. Yet no one matched the pure, seductive wallop of Cher". By contrast, her vocal performances during the 1970s were described by Eder as "dramatic, highly intense ... almost as much 'acted' as sung". First heard in the 1980 record "Black Rose", Cher employed sharper, more aggressive vocals on her hard rock-oriented albums, establishing her sexually confident image. For the 1995 album "It's a Man's World", she restrained her vocals, singing in higher registers and without vibrato.
