I went to a 5 seconds of summer concert it was amazing. There voices were amazing and Ashton was so good at drumming. HAPPY BIRTHDAY TO HIM. I'm going to remember that forever. Also Hey violet opened as well as one ok rock who are from Japan they were both so good. And in the parking lot we met this lowkey band called "a summer high" and I got a signed copy of their cd. You should go look them up they were really good. Also they are following half of the North American tour so look for them if you are going to one of the concerts. I'm so happy.
