As the case of Trayvon Martin continues to draw national attention, a group of R&B stars and celebrities led by Chaka Khan has come forward with a tribute single and PSA in honor of the slain 17-year-old.
Khan and her collaborators, including Kelly Price, Eric Benet, Kenny Latimore and The X Factor's Stacy Francis, recorded a new rendition of her 2007 song "Super Life" as a part of a public awareness campaign. A video PSA of the singers and other celebrities, including Angela Basset, Boris Kodjoe and Terry Crews, in which they all wear white t-shirts bearing the phrase "Super Life: Fear Kills Love Heals" was also posted online.
Martin was shot and killed in Sanford, FL, by neighborhood watch volunteer George Zimmerman in February. He was unarmed and on his way from the store when Zimmerman pursued him on the grounds that he looked suspicious. In a resulting scuffle, Martin, who was carrying only a bottle of iced tea and a bag of Skittles, took a fatal bullet to the chest. Zimmerman claimed self-defense and was not charged with any crime by the Sanford Police Department. A grand jury and the United States Justice Department are investigating the case.

"The song tells how love heals and it's about being ethical and honorable even when life can be so short and unfair,” one of the song’s participant’s, Stacy Francis, told The Hollywood Reporter. “The biggest thing for me was, I think it's horrible that someone can throw flour on Kim Kardashian and be prosecuted for it, but this [George Zimmerman] guy… it's not a good sign of where our society is at. So we all have to do our part and I'm using my voice to help in any way I can."
