Sean Don and La Flame join forces. During his show-stopping set at Lollapalooza over the weekend, Big Sean previewed a new song featuring Travis Scott.

The high-energy track features Auto-Tuned vocals from Travis, as well as braggadocios bars from Sean Don. “This is not a drill, it’s the real thing,” he raps. “I don’t want the head unless your mouth is real clean / Made my blueprints so my life got no ceilings / I create the energy that they keep stealing.”

Standing in front of a cross and stone blocks, the Detroit spitter stopped the track midway through his set and announced that he “just wanted to preview that shit.” No word yet on when or where it will be released.

Sean and Travis have collaborated on a slew of tracks in the past, including “On Everything,” “Don’t Play, “Workin,” “10 2 10 (Remix),” and most recently on “Champions.” The duo is also said to be working together on G.O.O.D. Music’s much-discussed Cruel Winter.

Meanwhile, Sean’s I Decided. LP is still making waves. In fact, the chart-topping LP currently sits at No. 63 on the Billboard 200.
