i went to the one in Madison, and I would have to agree.
the songs were dope as fuck but the crowd was LAME. literally had no fun there because the rest of the crowd wasnt really into it. i would imagine it'd be an insane show with a good crowd.
I went to porter robinson last summer and that was insanely fun, energetic and drugged out crowd. was expecting the same at 3LAU and was disapointed
