I had heard about this anime while visiting Funimation with my school club. We were able to sit in and watch them record some of the acting for a part of the episode where their at that music festival and they're in the tent complaining about the fans.
After that I tried watching it a few times but always dropped it after the 2nd episode or so because of my own reasons. So I finally managed to watch the whole thing and I have got to say I really enjoyed it. I feel a bit envious of them for getting popular when a band I was in at one point failed haha. Maho was a frustrating character...
