ARTMS posted an Official Dance Practice Ver. for 'Blue Blood' on the group's own channel at 21:00 KST on August 13, 2026. It runs 2 minutes and 29 seconds. Where the counters stand at the time of writing: 12,426 views, 1,572 likes and 88 comments.
The description does more than point at the video. It gives the album 'Hyper-Ego' with a release of 1PM KST on August 7, 2026, and still carries a pre-save link beneath it, then runs on into links for an app called Cosmo and its web shop, the group's website, Discord, X, Instagram and TikTok, closing with member hashtags for HeeJin, KimLip, JinSoul, Choerry and HaSeul.
In the middle of that block sits the tour. 'Art of BLUE BLOOD' is listed as Seoul on September 5 and 6, then North America as a single range, October 5 to 27, with a ticket link attached to both.
That second line is the one worth reading carefully. A three-week window and a ticket link is not the same as a show in your city — the description names no North American city and no venue at all, and it does not say how many nights fall inside the range. If you are planning around it, that is the shape of what has actually been put in writing here.
