Dr. Dre is releasing his first album in over six years. On Sunday (Dec. 12), the N.W.A. alum announced he will soon be sharing a new project called Casablanco with Floetry singer Marsha Ambrosius.

“I just finished recording an album with Marsha Ambrosius. ‘Casablanco’ I had a blast!!” Dre captioned an Instagram post, which sees him standing in front of an orchestra. “This is some of my best work!!”

On her own Instagram account, Ambrosius echoed the sentiment.

“I just finished recording an album with Dr. Dre ‘Casablanco’ I had an amazing time!!” she wrote. “This is some of my best work!!!”

Over on Instagram Stories, violinist Eric Gorfain also revealed some details about the forthcoming project.

“The cat is out the bag,” he wrote. “I spent this summer arranging strings for this entire album, reuniting with @drdre and @marshaambrosius. Casablanco is seriously good. Marsha is ridiculously good. Dre is The Greatest.”

Casablanco will mark Dre’s first album since 2015’s Compton, which was inspired by the N.W.A. biopic, Straight Outta Compton. He and Ambrosius previously teamed up on Compton cuts, “Genocide,” “All in a Day’s Work,” “Darkside/Gone” and “Satisfaction.” Prior to that, they collaborated on The Game’s “Start from Scratch,” Nas’ “Hustlers” and Busta Rhymes’ “Cocaina” and “Get You Some.”

Back in 2014, Ambrosius opened up to Complex about her and Dre’s collaborative relationship.

“We’ve been working together since like ‘05 and that’s been nonstop really since then,” she said at the time. “Whether it was The Game’s album or Busta Rhymes and his stuff and my own projects, it was just time. Timing is everything.”

Besides Casablanco, Dre also recently contributed to the “Grand Theft Auto Online: The Contract” soundtrack alongside Eminem, which will arrive on Dec. 15.
