Hello, I´m new around here, allow me to introduce myself.

My name is Roberto, I´m a 34 year old architect from Mexico City and I´ve been enjoying classical music since before I was even born. I love it, and since I have a form of synesthesia (I can smell and sometimes even taste it, go figure), I use classical music as an inspiration for many things.

The thing is I´ve been searching for two specific pieces featured in this videos I saw on Youtube recently. I´ve heard both but can´t actually remember where and would like to identify them. Could you please help me?
