In July 2001, Carey suffered a physical and emotional breakdown and was hospitalized in Connecticut on July 26, remaining under a doctor's care for two weeks. She attributed the collapse to exhaustion, and her Virgin Records deal, originally reported at $80 million, was subsequently bought out for $28 million.
Mariah Carey possesses a five-octave vocal range. She is known for her whistle register, melismatic singing style, and layered background vocals, and critics have described her voice as capable of moving from a rich alto in its lower register to extremely high whistle notes.
Carey handed her demo tape to Columbia Records head Tommy Mottola at a music executive's party in December 1988. Mottola listened to the tape on the ride home and immediately asked his driver to turn around, then spent two weeks looking for Carey after she had already left the event. He signed her to Columbia and assembled a team of producers for her debut album.
