Norwegian black metallers MAYHEM have checked in with the following update:

"Mayhem will not perform at the Unholy Fest in Czech Republic previously set to take place on July 22/23/24. Obviously this fest is a big scam! Sorry for the those who wanted to attend and/or already got ripped off by buying advance tickets.

However Mayhem is confirmed for the Rock City Festival set to take place in Fetesti, Romania on August 20th - 23rd. Go to this location for more information."
