Souhei Kano - his only work is Fractale, one of
best orchestral anime scores in recent years.
Yuji Yoshino - his only work is Spice and Wolf. His traditional/celtic style music would work great for certain types of anime.
Natsumi Kameoka - only work so far is KanColle. I'm sure she will get more work in the future. She is a great orchestrator and very popular right now.
