Destiny's Child is coming back to the clubs with music fans have never heard before. Mathew Knowles, the group's original manager and father of Beyoncé, revealed this week that the iconic trio is preparing a major 30th anniversary rollout centered on unreleased remixes. We're about to market a bunch of new remixes. Some you've never heard before from Destiny's Child, Knowles told SiriusXM's Page Six Radio hosts Danny Murphy and Evan Real on July 22. Knowles said fans won't have to wait long: the first drop is expected in the next 30 days. In a separate interview with TMZ, he said there are 10 to 15 remixes locked and loaded for the anniversary, with Beyoncé, Kelly Rowland and Michelle Williams all backing the release. The project will also include never-before-seen video and audio clips from the Destiny's Child archives. This is not a DJ compilation. Knowles stressed the vocals are original. We have a number of remixes that have never been released and we'll be putting those out soon, he said. They're with the girls. Now, we have some guest rappers on it, but the girls are on it. He described the collection as a mix of sounds: There's some that are dance mixes and then there's some that are just regular urban mixes. So, there's a combination. One guest he did name: Grammy-winner Missy Elliott. She's on one of them. I'll stop, Knowles teased. The announcement was timed ahead of *Destiny's Child: Iconic Reimagined*, a two-show tribute concert at The Bell Tower in Houston on Friday, July 24. The event transforms the group's biggest hits into a candlelight performance by a live string quintet while Knowles shares behind-the-scenes stories from their journey. It marks the latest resurgence for the group, which officially disbanded in 2006 after becoming one of the best-selling girl groups of all time. They rose to fame in the late 90s with original members Beyoncé Knowles-Carter, Kelly Rowland, LaTavia Roberson and LeToya Luckett, before solidifying as a trio with Michelle Williams. The trio stunned fans last summer when Williams and Rowland joined Beyoncé on stage for the final night of her Cowboy Carter and Rodeo Chitlin' Circuit Tour in Las Vegas, performing Bootylicious and Lose My Breath together for the first time in years. If released, the anniversary collection would be the group's first music since 2004's *Destiny Fulfilled*. Their only previous remix album, *This Is The Remix*, was released in 2002 and featured reworks from The Neptunes, Timbaland, Missy Elliott and Wyclef Jean. Knowles said it is still undecided whether the new remixes will arrive as a full album or as a series of singles, but confirmed the 30th anniversary plans are active and that talk of a potential reunion tour has not been ruled out. No official title, tracklist or release date has been announced by Columbia Records or Parkwood Entertainment.
