I think this is a Discordance Axis shirt but it may be a Gridlink or Hayaino Daisuki shirt. There is a reference to Grindcore Ninja Commando Team on the DA album The Inalienable Dreamless so I’ll go with that. The photo didn’t come out too well as the shirt is a brighter blue in real life.
I bought it off Jon Chang (or maybe his wife) at MDF 2010 as they had second hand shirts for sale for a brief period in the tiny booth inside Sonar. I think it was just in a box of mixed up clothes and I wish I dug a little deeper as who knows what was in there. I managed to miss most of Gridlink that day and walked in just as they were finishing which pissed me off to no end. Although it turns out they only played for 15 minutes so it’s not surprising I missed them.
If anyone can translate the Japanese please feel free to post a comment.
