The set began with Clams Casino performing on stage by himself with his laptop. After about 15 minutes A$AP took to the stage. A$AP is the name of the collective group, even though one member A$AP Rocky was billed.
The Harlem-based group was definitely a departure from the rest of the bands playing, rapping about drugs, swag and sex, but also spreading a general message of acceptance. At several points, they even stage dived and created a mosh pit, which was completely unexpected.
A$AP took to the stage with its many members. I believe this is A Twelvyy.
A$AP Rocky took to the stage next.
