Her voice could not have been mistaken for anybody else's. It would pierce through your entire being, giving you the chills, stopping your breath and slowing down your heartbeat. She shot to fame in the 1990s making hit after hit, including the most memorable I Will Always Love You. Her most remarkable performance though took place in 1991 at Super Bowl XXV at Tampa Stadium. Her signing, flawless, impeccable, and incredibly powerful shook the stadium and the world at large.
The sad part of her life is her very public struggle with drugs which she claimed to have won, at the expense of her inimitable voice. She died alone, on February 11, 2012, most likely as a result of a drug overdose. In an interview with Diane Sawyer ten years ago she confessed, "My greatest devil is me. I'm either my best friend or my worst enemy." Below you can watch Whitney's legendary performance at the 1991 Super Bowl, and her 2008 performance, shortly after the rehabilitation program.
PS: You can watch her performance after the rehabilitation program here. The difference is drastic and depressing to hear.
