Roger Waters closed the Coachella Music Festival with the timely reminder that Senator Clinton is just another brick in the wall. 

INDIO, Calif. (AP) — Roger Waters brought Coachella to a close with an epic two-set performance that included playing all of "Dark Side of the Moon" and unleashing a giant inflated pig into the night sky.

The pig, which was led above the crowd from lines held on the ground, displayed the words "Don't be led to the slaughter" and a cartoon of Uncle Sam wielding two bloody cleavers. The other side read "Fear builds walls."

The underside of the pig simply read "Obama" with a checked ballot box alongside.

Rogers had already tipped his hand when, following the Texas primary, he politely referred to Senator Clinton as ghastly:

Of course, nobody sets out to be ghastly.  But sometimes too many harsh blows in life, too much betrayal, and your youthful idealism lies bleeding by the wayside:

There is no pain you are receding
A distant ship, smoke on the horizon.
You are only coming through in waves.
Your lips move but I can't hear what you're saying.
When I was a child
I caught a fleeting glimpse
Out of the corner of my eye.
I turned to look but it was gone
I cannot put my finger on it now
The child is grown,
The dream is gone.
I have become comfortably numb.
