Death Grips cancelled their Saturday Lollapalooza set after no showing a festival afterparty—which ended in fans trashing a drum kit.

No one is completely sure just what went on on Friday night that caused Death Grips to bow out of their scheduled appearance at an official Lollapalooza aftershow.

The band was set to headline a showcase at Chicago's Bottom Lounge and, according to Pitchfork, no one announced the cancellation until late into the night.

The odder element of the night, however, was that (before the band was announced a no show) the venue played recordings of Death Grips songs and the stage was already set up with a strange backdrop.

The backdrop consisted of a Gmail screenshot of what appeared to be a suicide note written by a fan. The note read:

SUBJECT: ready DATE: July 9

I am ready to take my own life. Many bad experiences led me to this dark void that I am locked in. Maybe by my own hands? I don't really care anymore. I just wanted to say thank you for showing me the other side. the side that is locked away deep inside a person. I am mad. Mad all the time and depressed all the time. I can't take it. I'm not afraid of dying but i am afraid that I can't hear DG in the after life if there is such a thing. I don't know, but I hope your music transcends to the unknown. A place where DG's essence exists. A place where art exists. I love art. That's the one thing that kept me alive? this long. So just to ease minds, DG didn't "influence" me to do this. this is my own fucking choice. but thanks for making my life a little better. you're my absolute fave and I will fight the gods if they don't allow me to follow DG's efforts can't see Earth. Anyways, continue doing great things. I love you Stefan, Zach, and Andy.
I will be watching.

After a Bottom Lounge staff member finally announced that the headliners would not appear, angry fans reportedly went up on the stage and trashed what appeared to be Zach Hill's drum kit.

Lollapalooza spokeswoman, Shelby Meade, later told the Chicago Tribune that "[Death Grips] chose not to arrive in Chicago" and that Bad Things (Olympian snowboarder Shaun White's band) would take over for the absent act.

No word from Death Grips on the reason for the cancellations or the meaning behind the mysterious fan note.
