This video was one of the reasons i got attracted to VFX in the first place.
The masking part is awesome.
I'd like you to watch the video as a whole cuz its one of the classics by System Of A Down [S.A.O.D]
But just in case you are like my mom, who slaps me everytime i start banging my head to the bass and considers this kind of music as a head-ache, I managed to note down the exact timings in the video that has the masking part.
00:58 to 1:09
1:54 to 2:03
2:18 to 2:23
3:02 to 3:06
I couldnt find the case study of the video though.
Okay Now um off.
Keep Rocking \m/ ;)
