Sayonara Memories, from 2nd studio album by Supercell, piano arranged by @Animenzzz , played by Richard Yang on Yamaha N1X with Garritan CFX VST.
Sayonara Memories, according to Animenz, is “one of the most advanced arrangements” he ever made (at that time), earning a spot in his Top 10 Most Difficult playlist. Once you play it, you can understand why. There are so many technical runs, jumps, etc that make getting through the piece in full extremely difficult. I believe My Dearest is still a bit more difficult than this though, which you can find my performance in my Animenz playlist.
As with all of my performances, I have my own interpretation, so the tempo, dynamics, etc may feel quite different from the original recording. Simply put, I play the way I like it.
