this is dirty man, the bass is coming through a little muddy and demanding in the lower frequency spectrum. but never theless bigg tune this bro, love that beat on the intro
Intro: sick beat in the intro! i like it. the bass line is great!
drop: atmospheric! amazinG!
main part: something between breakbeat, dubstep and dnb... i like that style!
Like it, beat is indeed really nice, I also like those extra drums coming in at 2:14
You've also made great use of samples (or recordings) , like that real bass guitar (<- i think) at 3:00
Overall great production, just work on what lucid said ;D
