Arch Echo have canceled their appearance at this year’s festival. The band will issue their own statement and I refer you to them for further questions or comments.
A replacement will be named as soon as possible….again.
Arch Echo statement:

Hey all, a quick update regarding our upcoming spot at Prog Power USA. Due to personal reasons, the band has made the difficult decision to pull out of Prog Power USA and a surrounding spring tour we had not yet announced. While we are sad to not be seeing you there, we are very excited for the bands that will be attending and we hope to see you in the future. Thank you to the Prog Power USA team for everything that they do and we wish you a phenomenal festival.
