Arch Matheos played this year’s Keep it True festival in Germany.  This must have been a monumental experience for all who attended. Here’s a fan video of Guardian.

And here is the Arch Matheos setlist from Keep it True:
Neurotically Wired
Midnight Serenade
The Sorceress
Stained Glass Sky
Damnation
The Apparition
Any Given Day/Strangers Like Me
Guardian
Encore:
Epitaph
Exodus
I cannot believe how great this setlist is. [...]
