Meshuggah

Album:

Catch Thirtythree

Non-physical smothering. 
Asphyxiation by oxygen hands
Drowning in the endless sky. 
In ever-downward dive, only to surface
The sewage of indecision, 
On which all sense of self is afloat
The vortex-acceleration a constant. 
Resolute in purpose its choking flow
