As a young musician, this stuff really blew my mind the first time I heard it. I still get blown away by the technicality of it all. Seeing this for the first time recently really exemplified how much of a transcription and articulation feat this truly is. I remember listening to this song, and hearing from the friend who first introduced me to it that it had something to do with the Thumper parts in Bambi, but I never thought to do any research into it beyond that. I figured it would take me going to rent Bambi and arbitrarily lining the song up like the 3rd lion's roar for 'The Wall' and Wizard of Oz...Sometimes I forget where, or maybe in 'what age' I'm living - gems like this are only a few keystrokes away, and sometimes they find you.
