I don't have reliable information about "Merzbow + Hexa" as an established or widely documented collaboration in my training data. Merzbow is a well-known Japanese noise musician, but I cannot verify details about a specific project or collaboration with "Hexa" or confirm its current status.
I'd recommend checking the artists' official websites, social media, or music platforms like Bandcamp or Discogs for an accurate biography to use for your merchandise store.
