Does anyone know the violin song that Toshiya Miike plays after Kousei's performance in episode 13? Does anyone know the violin song that Toshiya Miike (Mikke-kun/-san) plays after Kousei's performance in episode 13? I wish I knew the exact time but I don't. I've searched everywhere trying to see if anyone figured it out or knew what it was but no luck. Help please?
It seems to be: 

Elgar: Violin Sonata in E minor, Op 82 Vengerov

Or [エルガー： ヴァイオリン・ソナタ ホ短調 作品82 ヴェンゲーロフ] if in Japanese.

Here is a link to the piece: https://www.youtube.com/watch?v=HOutOaSMHZ4
