I bought these tickets sort of on a whim and didn't know a lot of !!! songs going into the concert (which usually means I don't enjoy the show as much). What I had listened to I thought was just ok. My friend and I almost decided to bail. I'm so glad we didn't.
First, the music was incredible. The band sounds completely different live from their recorded stuff (the recorded stuff sounds much more rave-y than it does live) and is, in my opinion, much much better. It was really the first concert I'd ever attended where I enjoyed every song, even the ones I wasn't familiar with (which was most of them).
Second, Nic Offer -- lead vocals -- is one of the most charismatic performers I've ever seen and, along with the rest of the band, were an absolute blast to watch. I couldn't stop smiling; it was just such a fun concert.
Third, awesome seeing them at MHoW, relatively small and intimate. Nic came into crowd multiple times. He even danced with me!
Overall, an amazing show. I go to a lot of concerts; I think this made all-time top 5.
