August Burns Red is planning a 10th anniversary tour for Constellations, per sources. The tour is scheduled to take place in February/March 2019. View the rumored lineup below.

According to Reddit user u/Jamal_x, he spoke to Fit For A King’s merch guy who told him that Miss May I, FFAK, and Crystal Lake (their first time coming to the USA!) with an unknown headliner. The merch guy also described the “unknown” headliner as: “heavier/bigger than Beartooth, a lot of breakdowns, one of the first users of "off melody breakdowns."

Matt Greiner was on the In A Nuttshel Podcast (Alex from ADTR) a while back and said the following at 19:00 in the episode:

“I actually was just going through my pictures on an old hard drive, which was such a pain in the butt. I have to dig up old pictures from [the] Constellations era, because, we are talking about doing a 10-year tour for that record. And, we’re putting together a photo book for it.”

You may think these are unrelated to each other but all of the bands mentioned have a clear schedule with the timeframe of the tour.

EDIT: I was wrong about the tour being for Constellations but all the other information here is correct.
