Brace yourselves, people. What you’re about to hear is likely Whitney Houston’s final recording. Ryan Seacrest debuted the track, a duet with Jordin Sparks, via his radio show on Monday. “Celebrate” comes from the soundtrack to Houston and Sparks’ remake of Sparkle, due in theaters this August, and was written by R. Kelly. It’s got a funky, disco vibe, and if Sparks’ voice is silk, Whitney’s is velvet: deeper, softer, throatier. It carries the weight of the late singer life, her highs and lows, enveloping and grounding the song, while Sparks’ vocals soar.
