The Danish band was set to perform at the annual music festival which is set to take place on September 9-12 in Atlanta, Ga. and it would have been the band's very first live appearance in the U.S.

The group and Olesen both released statements about the turn of events. The band says, "It is with deep regret that we have to announce the following: Anubis Gate will have to cancel this year's Prog Power US Festival. This is an event that we have been looking forward to for years now, but due to unfortunate health problems within the band, we see no other way but to cancel the show.

"We hope for your understanding and pray that all who have been looking forward to the show and bought tickets will accept our deep-felt apologies. It is really out of our hands, and even though we should have wanted a replacement for Kim it is impossible at this hour. Hopefully we'll see you sometime in the future, when the "clouds have passed".

Kim Olesen explains, "Dear Anubis Mates. I have recently been diagnosed with a deep depression and panic anxiety (meaning that I suffer from heavy panic attacks). It is with the greatest of regrets that I have had to realise that I am simply not well enough to go through the logistics of playing so far away from home. I was looking enormously forward to playing in front of you all, indeed it would have been a highlight of my career as a musician. And, of course, I was also looking forward to meeting so many people I know from social medias, it would have been a hangout that I would cherish for the rest of my life.

"But the reality is that even though I am in treatment and the depression side of things has seen progress, the panic anxiety is taking much longer to subside than I had anticipated and hoped for. My doctor and therapist's verdict is clear; the risk I would be taking is that my condition could become chronical. I am glad that my fantastic bandmembers Henrik, Michael and Morten have been supportive through what is a very hard time for me, as has my family, friends and all other relations as well.
