In the way that the Internet has scrambled pretty much everything, it has remade the textbook of oddball rap. For this generation, the tree of influence is short and irregularly shaped: Soulja Boy for self-started, Internet-driven fame; ASAP Rocky and the rest of the ASAP Mob for flamboyance and for eradicating regional loyalty; Chief Keef for the disassembly of traditional ideas about verse structure; Young Thug for radiant weirdness and genuine indifference.

This set of reference points doesn’t quite result in a unified aesthetic, though. Instead, it is a license for eccentricity, building a new generation raised almost exclusively on misfit elders, rappers who were (and sometimes still are) maligned for their unconventional approaches.

Their children are, to a man, even stranger, as seen at two concerts with loads of thematic overlap last week: Lil Yachty, who performed Tuesday night at Webster Hall’s Marlin Room, and Lil Uzi Vert and Playboi Carti, who shared a bill Wednesday night at S.O.B.’s.
