Quavo and Ty Dolla $ign, assemble! On Friday, the pair of musicians linked up with Brian Tyler‘s Are We Dreaming for “If I Fall” — a futuristic, rock-rap “synergistic” anthem from the upcoming Transformers One soundtrack.

“I’m in my prime, Optimus (Optimus), I’m goin’ big, Megatron,” raps Quavo in the song’s third verse. “I’ma sting, Bumblebee, now crown the king, hope you proud of me.”

The new single, which includes Tyler’s vocals in the chorus, is set to be featured as the closing credits for the upcoming animation film, out Sept. 20, starring a massive voice cast that includes Chris Hemsworth, Brian Tyree Henry, Scarlett Johansson, Keegan-Michael Key, and Steve Buscemi.

“I started writing the song ‘If I Fall’ as a personal way to both express my gratitude to those who truly lifted me up when I fell down in life and a rebuke of those who turned away,” said Brian Tyler, who composed music for the film, in a press release. “This concept is the core story of Transformers One, so it’s a synergistic song.”

“I was blessed to have both Quavo and Ty Dolla $ign contribute their incredible vocals to the track — it turned out so dope!” he added. (Tyler has been behind some massive film compositions, including several Fast and Furious films, The Super Mario Bros. Movie, 2018’s Crazy Rich Asians, and several Marvel films.)

The new single reunites Ty and Quavo, who’ve collaborated on numerous tracks in the past. The pair rapped together on “Long Time” from Ty’s 2016 album Free TC and again on “Pineapple” with Gucci Mane on Ty’s Beach House 3 in 2017. The pair also joined Machine Gun Kelly on the rocker’s “Trap Paris” in 2017 and Chase B and Travis Scott on “Ring Ring” last year.

The “Paranoid” artist also collaborated with Quavo’s former group, Migos, on “White Sand” from the group’s Culture II in 2018 and “?? (Where)” from Ty’s 2016 album Campaign.
