TSlayer - Dream Theater - Instrumedley (OneTake Drum Cover)

I heard this exact track (not the one from Budokan) when I was in my primary school, studying with my teacher. He showed me this 2003 drummer festival disc, and we learnt the Beatles cover songs from Mike Portnoy and his fellows in Yellow Matter Custard. I didn't know the last was Dream Theater, but I was blown away by the complexity and intricacy of the music. And now here it is, audio and video same one take, enjoy :)
I am a 19yo drummer from China. The tracks and videos are simultaneously recorded, and I don't use tabs - I just listen to the songs and end up where I am in the video.
Comment for any advice.
Hope you guys like it. Please subscribe if you'd like the video. : )
