Wow, really impressed. Progressive was such an unexpected song, since it's forgotten most of the time, even on Kalafina's own lives. So it's even more shocking to see it on a non-Kalafina (?) live.
Tbh, when I saw the setlist I was worried because of Hikaru not being able to perform it well enough. But WOW, it turned out way better than I could expect. Hikaru shouts a little on the beggining of the chorus, but otherwise sounds really good despite the awful sound quality (what's wrong with Mezamashi lives? Last year the audio was awful, but this year I cannot even hear the music background. At some points it even sounded like an a capella cover...).
Hyakka Ryouran was also a pleasant surprise. Chorus was the weakest part of the song for me, because Wakana sounded too weak compared to Keiko and Hikaru, but here her was more dramatic and intense. I like it better that way.
There's also some super short recording on twitter of Keiko's part and they're GORGEOUS (cannot find it anymore). Her voice is soooo deeep and perfect
Wrote too much for such a short report but I really loved it, sorry asldkfjlsfdlasdfj
