SAN FRANCISCO — Kinetic energy can be a real phenomenon when you’re standing at the edge of a mosh pit, anticipating a giant shove in the back as A$AP Ferg introduces, “Shabba.” You had better be prepared to absorb that energy and give it right back on A$AP Ferg’s Mad Man Tour, which arrived at the Warfield Tuesday.

Ferg is touring in support of his latest mixtape, “Still Striving.” Fresh off the heels of 2017’s A$AP Mob tour, the “Trap Lord” brought the intensity for his solo showcase. After easing the audience into the set with several tracks off his new album, such as “Coach Cartier,” “Tango” and “Olympian,” Ferg hit his stride with “Nasty,” and its memorable chorus sample from JT Money’s late ’90s Dirty South hit “Who Dat.” But it was Carnage’s “WDYW” that established and confirmed that this was, indeed, a trap party—using Lil Uzi Vert on the backing track to build the crowd up before maniacally launching into his own verse just as the bass hit and gave the crowd the full authority to dismantle the dance floor.

A giant circle formed on the floor two songs later, at the start of “East Coast,” as A$AP Ferg said, “Everybody open this shit up!” Pure madness reigned from then on. Feeding off the crowd, Ferg launched into hit after hit: “Shabba,” “Work,” “New Level” and “Plain Jane,” the first single off “Still Striving.”

Young artists IDK and Denzel Curry opened the show, and their ability to feed off each another while sharing the limelight was what prepped the audience for the rest of the night.

IDK returned to the stage after his set for, “Uh Huh,” his latest collaboration with Curry, which aptly references the tag team wrestling duo Undertaker and Kane. The floor shook from their combined efforts on the mic before the duo transitioned to their first track together, “No Wave.” The surprise of the night came when their DJ dropped Nirvana’s “Smells Like Teen Spirit.”
