Two years after she learned English, Dion made her debut into the Anglophone market with "Unison" (1990), the lead single having originally been recorded by Laura Branigan. She incorporated the help of many established musicians, including Vito Luprano and Canadian producer David Foster. The album was largely influenced by 1980s soft rock music that quickly found a niche within the adult contemporary radio format. "Unison" also hit the right notes with critics: Jim Faber of "Entertainment Weekly" wrote that her vocals were "tastefully unadorned", and that she never attempted to "bring off styles that are beyond her". Stephen Thomas Erlewine of AllMusic declared it "a fine, sophisticated American debut". Singles from the album included "(If There Was) Any Other Way", "The Last to Know", "Unison", and "Where Does My Heart Beat Now", a mid-tempo soft-rock ballad that made prominent use of the electric guitar. The latter became her first top-ten hit on the US "Billboard" Hot 100, peaking at number four. In 1991, Dion was a featured soloist on "Voices That Care", a tribute to American troops fighting in Operation Desert Storm.
