Abstract Thought

Abstract Thought (Instrumental) is included in "Inside Out Soundtrack". A bit disturbing, it creates anxiety literally in 20 seconds, causing us nervous look around. It has many different non-musical sounds, which even make it look like a cacophony. It was teetering on the brink of a mixture of sounds and of music and till the end does not give us the answer to what it was. Even more than that – it includes the pipe here too, making it like jazz. Still, cacophony is a closer definition.
