Whitney Houston, 'The Voice,' was one of the best-selling music artists of all time. Trained in gospel and influenced by her mother Cissy Houston and cousin Dionne Warwick, Whitney possessed a five-octave range and perfect technical control. Her rendition of Dolly Parton's 'I Will Always Love You' for the film 'The Bodyguard' (1992) became one of the best-selling singles in history, spending 14 weeks at number one. She was the first artist to have seven consecutive number-one singles on the Billboard Hot 100. Houston's ability to blend gospel power with pop accessibility set the standard for every 'diva' who followed. Despite her personal struggles later in life, her performance of 'The Star-Spangled Banner' at the 1991 Super Bowl remains the definitive version of the national anthem.
