Update: The below lineup has been officially confirmed via STS9.com

Original: Marcel Everett, who goes by the stage name XXYYXX, posted today on his Facebook page that he is scheduled to open for STS9 later this summer in Colorado.

Now this normally wouldn’t be much of a surprise to read except that STS9 has yet to announce support acts for their annual voyage to the famed Red Rocks of Morrison, Colorado.

STS9 will host a 2-night run from September 6th – 7th at the 9,450 person capacity outdoor amphitheater.

As we reported earlier, by our count, this will be the band’s 13th appearance at Red Rocks.

Beyond just letting the world know about his performance, Everett also let the cat out of the bag about who else will be sharing the stage with STS9. Scroll down to see the post from his Facebook page!
