The 2015 Lifetime film Whitney was met to mixed reviews but an upcoming authorized documentary of the same name hopes to give a deeper look into the life and career of legendary singer Whitney Houston.

Directed by Kevin Macdonald, the Whitney documentary is set to premiere on July 6 and will offer several new glimpses into the songstress' life, including previously unreleased music and never-before-seen footage, Variety reports. The movie will also feature live performances from the singer's career and has the support of Pat Houston, Whitney's sister-in-law, as well as the Houston estate.

“I approached Whitney’s life like a mystery story; why did someone with so much raw talent and beauty self-destruct so publicly and painfully?” Macdonald said. “I was lucky enough to have the support of Pat Houston and the Whitney Houston estate in this quest. They entrusted me with the ‘keys to the vault’ while giving me complete freedom to follow the story wherever it went. At heart, Whitney is an intimate family story that reveals a new side to a woman that even her most die-hard fans never knew.”

The upcoming documentary will also feature original studio recordings from Houston, as well as a capella versions of some of her biggest hits. Whitney is executive produced Patricia Houston, Nicole David, Zanne Devine, Rosanne Korenberg, Joe Patrick, and Altitude Film Entertainment’s Will Clarke, Andy Mayson, and Mike Runagall.

Last month, fans paid tribute to Houston on the sixth anniversary of her death. On Feb. 11, 2012, the iconic singer was found underwater in the bathtub of her room at the Beverly Hilton in Beverly Hills, Calif. The official coroner's report revealed Houston died of accidental drowning.
