His fans have offered some guesses as to who it could be.
Migos' sequel to CULTURE has an exciting executive producer, according to Quavo. The Atlanta rapper, who recently hinted that the trio's new album would receive its first single in the near future, shared another update on Twitter Saturday. "C U L T U R E II WAIT TIL U SEE WHO EXECUTIVE PRODUCED IT!!" he wrote.
Of course, all fans could do was guess, which is exactly what they did in Quavo's mentions. A mix of jokes (Asahd, Saint West) and legitimate possibilities, three names that seem plausible were brought up.
Metro Boomin: The producer of Migos' biggest hit to date "Bad and Boujee," who also recently collaborated with the group on Gucci Mane's "I Get The Bag," as well as a number of other records from the members, solo or otherwise. He's previously executive-produced Future's Monster tape, Drake and Future's What A Time To Be Alive, and 21 Savage's Savage Mode, among others.
Travis Scott: Travis co-executive-produced his own albums Rodeo and Birds In The Trap Sing McKnight. At one point he was rumored to be executive-producing Rihanna's ANTI. He and Quavo have been working together on an upcoming joint project.
Kanye West: In September 2016, Migos signed a management deal with Kanye's GOOD Music. Kanye has previously executive-produced projects for artists on GOOD Music including Kid Cudi's Man On The Moon and Common's Be. He's currently working with Pusha T on King Push. Kanye has also served as exec producer on his own albums as well as Jay-Z's Blueprint 3. He worked directly with Quavo on the GOOD Music crew track "Champions" in 2016.
It may turn out that none of these artists currently hold the title of executive producer on CULTURE II, but it would be surprising if at least two out of three didn't contribute in some way.
As for when the project will arrive, that's still up in the air. In June, Offset suggested the album would be out In October, which would mean it would have to see release next week. For the most part, the various members have simply been saying the album is "coming soon" over the last few months. Though much has been left ambiguous, one thing does seem set in stone: Cardi B, the Bronx rapper behind the summer's biggest single "Bodak Yellow," as well as girlfriend to Offset, will make an appearance on the project.
