A shrill of excitement ran through the crowd, when they heard that Twenty One Pilots and ASAP Rocky Rock would perform at the 2015 MTV VMAs.

The trio, who had never even met until two days ago, left the audience awestruck when they hit the stage together.

"It was evident the matchup wouldn't crash and burn," fuse.tv reported. "Thanks to a hodgepodge of songs from both artists' albums, including Twenty One Pilots' "Lane Boy" and Rocky's "L$D."

Drummer Josh Dun supercharged the gig, while Pilot Vocalist, Tyler Joseph and Rocky traded off verses on each other's songs to create magic.

The collaboration was described as a "scorcher," Entertainment Weekly said. "While the energy of most performances don't quit come through on the small screen.... They (Twenty One Pilots and ASAP Rocky) flowed through "M'$," Rocky's tribute to the late A$AP Yams and fan-favorite "L$D", Twenty One Pilots' "HeavyDirtySoul" and "Lane Boy," the report added.

Twenty One Pilots and ASAP come from diverse musical backgrounds. Twenty One Pilots is one of the buzziest live bands that rely on rock-infused electro pop and alt-hip hop. While, ASAP was the guy who wrapped in Selena Gomez's "Good For You." But, they shared a commitment to tear up the stage.

"It ain't about mashups, it's about creating something rare," ASAP said of the performance.

Tyler Joseph, Twenty One Pilots' front man described ASAP Rocky as their "tastemaker." He told that Rocky was someone who was ahead of the game and knew where the next fad was going.

Flashing strobe lights amped up the drama, while the duo's rhymes struck the crowd like bolts of lightning. After their performance, the audience as enthusiastic as ever.

"When two of the biggest names in rock and rap (Twenty One Pilots and ASAP Rocky) get together, music magic like this just happens," Hollywood Life reported. Taylor Swift's "Wildest Dream" and "Bad Blood" duet with Nicki Minaj was also one of the standout performances at the 2015 MTV VMAs.
