I am not that much a Fan of Joelles voice. I had high expectations but something in it bothers me.
I'm not of a fan of her when she's singing in her chest voice, usually Japanese songs. She adopts an overly bright and very nasal quality when she sings, in contrast to her absolutely beautiful head voice in other Kajiura songs (her performance of Godsibb is still legendary to this day).
Unlike most members here, I really dislike Eri Itou's voice. There's just something about it that reminds me of my grandma singing and not in a good way. Hanae and Remi are infinitely superior in tone for me.
I think a lot of people dislike Yuuka's voice here but despite the nasality, I've come to appreciate her songs (and her voice) a lot more recently. I think a lot of FJ Yuuka songs rival the best Kalafina songs, like Yorokobi (in my top 5 Kajiura songs of all time), aikoi, inside your heart, Seiya, destination and Hitomi no Chikara. All these songs just wouldn't be the same without Yuuka's voice, though I would love for Keiko to cover more Yuuka songs in FJ lives.
I still like Hikaru's voice, to this day. She's been my favourite Kalafina member since the very beginning (ARIA is the whole reason I even started obsessing over Kajiura's music). Yea her voice isn't as great as it once was but I love it all the same.
Same with my opinion on Kalafina too. I don't know why most people here dislike Kalafina (especially their later releases) but I loved Far On The Water just as much as their other albums. Musunde Hikaru is my favourite Kalafina song of all time, and every album-original track is still very good. Not Red Moon-tier, but like a 8/10, if RM is a 10/10 and SH was a 9/10. I certainly liked it more than After Eden's original tracks, Destination Unknown carried the whole album. I wish Kajiura would cover Kalafina songs in YK lives, it's been 5 years since they disbanded and her setlists are getting VERY stale.
I dislike almost every Kajiura collab since Kalafina's disbandment. I initially liked the Aimer and LiSA songs when they first came out, but they're just so uninspired now. If you thought Kalafina was "same-y" her collabs are even more so. Kalafina's disbandment is the reason I even tried listening to new artists (I listened to nothing BUT Kajiura music in my teens) and now there are so many amazing Japanese composers that I like more than Kajiura currently. I still think Kalafina was her best work, like ever (and no group has ever had as good of music as Kalafina, even until today), but Guilty Kiss is the first group in a very long time to have rock songs that can rival Kalafina's bangers like Destination Unknown, Magia and Mata Kaze.
(btw if you haven't listened to Deep Sea Cocoon, Kowareyasuki, Shooting Star Warrior and Strawberry Trapper, you haven't LIVED).
