There is certainly a gray cloud looming over the 2012 Grammy Awards, which are set to air in just a few hours on Sunday (February 12). One day after music icon [article id="1679049"]Whitney Houston was found dead[/article], the show will pay tribute to the six-time Grammy winner.

As A-listers hit the red carpet at Los Angeles' Staple Center, they have been remembering the big-voiced talent for her undeniable gift.

"She had the swagger and she had the voice," Diplo told MTV News during our pre-show live stream. "I was listening to a bunch of records last night, and I was amazed at how deeply I felt about her records as a child."

The producer noted that her contributions to music of all genres still resonated today, thanks to her ability to bust genres wide open and make them all her own. "She had that persona that pulled of pop music and urban and R&B in a way that no one else could do it," he added.

EDM producer A-Trak said that it wasn't just her catalog that made her iconic, but also her voice. "Just pure talent, incredible voice and the whole package, the personality the presence," he said, "once in a generation, spectacular talent."

Jennifer Hudson and Houston's longtime friend Chaka Khan are expected to lead [article id="1679040"]a tribute to the late icon[/article] during the Grammys. The show's executive producer, Ken Ehrlich, said in a statement, "It's too fresh in everyone's memory to do more at this time, but we would be remiss if we didn't recognize Whitney's remarkable contribution to music fans in general, and in particular her close ties with the Grammy telecast and her Grammy wins and nominations over the years."

MTV News' Sway and James Montgomery will be live from the Grammys red carpet all evening to get reactions from music's biggest stars on the death of Whitney Houston. Watch reactions and remembrances at MTV.com.
