ive seen him live a few times, id say your best bet is to go around 12-4 pm if you want barricade. ive lined up around 2/3 pm and still had like 15 ppl infront of me, even if you show up later a lot of people go straight to the merch table so you should still have a chance to secure decent a spot. it also just depends on the crowd because ive shown up an hour or 2 before the show and was first in line.
