Rihanna released the video for her second single off Unapologetic last night, the beautiful ballad 'Stay'. The track is one that Rihanna performed on SNL and on the Grammys Sunday night. The song is by far her best vocal performance to date, and it's one of those that I think will restore some people's faith in her. Her tumultuous relationship with Chris Brown has overshadowed much of her career, and now that she's back with him it's making it even harder for people to respect her. On Sunday night she gave a flawless vocal performance, her best ever. The video for 'Stay' is beyond simple: it's Rih Rih singing in a bathtub, and her emotions are conveyed through her face. That's basically it, but it's powerful and you feel the anguish and the hurt that Rihanna is going through. It's nothing spectacular, but this song is a landmark moment in her career.
