Both days seem pretty good, though day 2 seems like the more enjoyable experience. My only complaints, just based on knowing the setlist:
-Day 1: Remi singing the same songs as always (No Historia 3, no HF, no newest SAO movie), and no MATERIALISE with glorious Kasahara! DOUSHITE! The rest seems kewl.
-Day 2: No complaints hue.
I really hope they don't cut any song from the broadcast, or if they do, they include it in the inevitable BD release.
Also, all that previous talk about she who shall not be named made me remember to thank the gods she was not a surprise guest. May it continue that way plox.
This is so, so wrong lol. Bright and dark sounds can complement each other. Keiko's buttery-smooth voice can blend with whoever she sings with, as long as there is effort to blend, which is not a problem with the current lineup. She had no problems blending with Yuriko on Canta per me and Himeboshi. No full duets with Joelle so far, but there were no problems when she sang low harmony for her like in Gaika, Beginning, and Parade. LiSA and Keiko didn't blend because LiSA didn't even try to fit the song's style (and no effort to blend), while Keiko did. They were on two completely different channels. And she didn't blend with May'n cuz she just plain sucks lol.
Also, Wakana's voice post-Red Moon IS bright, so you're argument kinda falls apart. It's not always as bright as Joelle's pop mode (who can sing darker, ex LORD, some solo lives), but it can and has been in a good chunk of songs. Hikaru's voice is also bright, with dark Hikaru being the exception, not the norm. Soooo, Kalafina pretty much proves that Keiko can sing with bright voices.
Honestly, I think some Kalafans think harmonizing and blending with others is some mystical ability that only works when singing with people with the red ribbon of fate attached to their finger lol. It takes work, but it's not impossible, and the current girls most definitely can do it.
