Looking for an AMV (Your Lie in April)

[Dargeron]

Hi guys! I recently saw a Shigatsu wa kimi no uso (Your lie in april) AMV that I really loved. I think it won a prize in one contest or another. Anyway, it was an instrumental AMV and the song (or one of the songs) was a violin version of Let It Go (from Frozen). In the beginning you could see Kosei's rivals playing, and it looked like they were the ones playign the music. Then Kosei and Kaori started playing in the same way.
I've tried everything I could think of, but I can't find it, so I decided to ask here... please help me out!!!
