I tried playing this on piano and it was out of tune. I detuned the keyboard to 427.2Hz and the note E at the introduction fell in tune. It has to be something with the playback, because they used a full orchestra.
No vocals but 6+ mins of pure instrumental heaven to get totally lost in, bliss. Listen to the breaks that happen at 2.36 and 4.36 and leads to a crescendo of energy at the end of this musical roller coaster of a journey. Pure instrumental heaven, nuff said!!!!!!!!!!
