Tchaikovsky – June (Barcarolle) Op 37b-6

I vividly remember how I found this music. That day, when I was young and strolling inside a CD shop, I randomly pick up a CD and ask for a test listening (ah these old days). I immediately felt this music. Tchaikovsky’s music is always very colourful but there’s this underlying sad, sad complex mood. I wonder, if this is because his personal experience from his sexual orientation?
