A little rough around the edges at times, but the timbre of her voice sounds just as wonderful as it did all those years ago. Assertive and confident, yet still capable of evoking emotion. I hope she's doing well.
Maybe instead of explaining damage voice this and that which isn't even part of the discussion you should answer why Hikaru should be replaced by Maya? Do you think replacing her can make Wakana awesome again?^ But if performances damage the voice, then whats the point of doing all these lives ? Its like becoming a [insert job] and starting to lose your skills overtime because you are doing that job (same for Wakana) . Maybe they should just stop the lives and just do studio releases like in the pre-kalafina days, and do 1 tour per year instead of 4. After all in most of these they perform the same songs again and again on the same cities too.
Do you have a source stating that Keiko wanted Kalafina to perform lives and and "forced" Kajiura-san to make them trio? I think the staffs wanted them to try perform lives and failing there and then but still persevere until they can control how they are now (Kalafina Record if I recall). With regards of Maya, I have a theory that she doesn't want how Kalafina sounded (Gothic-like image which is not kinda famous in Japan), just look at her dancing group and their song choices, coupled with her circumstances, so she left the group. So there's no choice but to make them a trio as they are now. I'm really sorry but I can see your statements blaming Keiko with Maya's departureWhy did Maya quit Kalafina ? Simple. She was 16 and living in Hokkaido. (this is the info I have) School was more important. Kalafina as a group remained nothing more than a studio act until HIkaru moved to Tokyo. It was then when the restless and rambunctious Keiko said to the others: Let's go do some gigs. Remember, their first gigs were in clubs of no more than 200 people. And they didn't sell out. Maya is way up there in the north, going to school. There was no way she could do any gigs with the others. So she bowed out. And also remember. YK didn't have a set idea of what Kalafina would be. She thought of it as a fluid concept with singers coming and going as she required to make a song the way she wanted it. Keiko is the one who solidified the group in to a performing act. She basically foreced YK to work with the trio as they are. Sure: add instruments here and there, add backing vocals here and there. So ,really, Maya wasn't a member of the solidified Kalafina. She was part of the fluid studio concept. And she flowed right out when the concept changed to a performing act.
As for constantly touring. That's the old school way of doing it to build an audience. Take a look at how the Rock bands of the 70s and early 80s did it and how they are doing it now. They tour. And TOUR and TOUR CONSTANTLY. They tour when they have no new material to promote. Kalafina is doing just that. Just like SCANDAL and MIWA and many others. They tour and tour and when they finish touring, they do more touring. I really think that if Kaori toured more, she could raise her profile and sell more music.
