Hello! Do you have any videos, clips, or audio of Wakana or Hikaru singing but before they joined FJ and Kalafina?
I am afraid there isn’t a lot.
As far as Hikaru is concerned, I don’t think there are any recordings from the time before she joined Kalafina. While she did a lot of auditions I don’t think she ever had any official gigs which could have been recorded. Aside from that we know that she appeared in a lot of CMs as a kid but there is really no way of knowing what sort of CMs those were. Finding them is next to impossible.
Wakana on the other hand has done a lot of stuff before she became a member of Kalafina but there is not much physical evidence of it I am afraid. The stuff I know about I have already posted in the past but I am happy to share it again.Space Craft used to organise events such as HerStories or Female Voice Party where many of their talents would take part (including Wakana and Keiko - since mid-2005). I have yet to come across a recording though. I actually doubt there are any out there. The girls would also occasionally appear as front act/special guest for Bon Bon Blanco (a girl group which was managed by Space Craft). There is a single video out there of Bon Bon Blanco performing “だいじょうぶ!! my friend”. The video features quite a bit of baby!Wakana (+Kaori+Yuuki Yoshida).You can find it 〈(•ˇ‿ˇ•)-→ HERE
Please note that at that time Wakana had already worked together with Yuki Kajiura as FictionJunction WAKANA. I guess you could say she “joined” FictionJunction at the beginning of 2007 (or late 2006).
Wakana also used to do a bit of chorus work for other singers but nothing noteworthy tbh, you can barely make out her voice in those songs.
You can hear Wakana’s higher harmonies in “Dattan Jin no Odori” by Norimasa Fujisawa. Wakana and Norimasa are actually long-time-acquaintances, they did a lot of voice training together before they debuted. You can also hear her in “Musuhi no Toki” by Haruka Tomatsu. And she got credited in SMAP’s album 「super.modern.artistic.performance」for the song “ひとつだけの愛〜アベ・マリア”. I think you can hear her quite clearly during certain parts of that song.
So yeah, it’s not a lot and none of the things I mentioned here are “new” per se, it’s all pretty well-known among fans. I wish I had a secret stash of baby!Kalafina recordings but alas, I don’t (。•́︿•̀。)
