Rachmoninoff would've heard this and thought to himself "meh, it's s'alright". The fact that this all is produced impulsively as an improvisation is what makes your recordings special. Sometimes I wonder... what would happen if adaMills decided to do an improv. and notate it into sheet music?
At first, this piece does sound like the ramblings of a college student taking Intro. to Musical Composition. Once it evolves, somewhere around 4mins., it starts to sound like a genuine expression of whatever it was you were going for; it really sounds not just like improv., but it sounds like thematic development. Good job as always adaMills.
