I kid you not... (think about it...) Pramtera?!
When you're looking at a website store, you should spot some examples of baby and child merch. I've given several examples before, so add this legends of thrash metal merch to the list.
For legacy or established acts like this it makes perfect sense. Pantera broke through in the early 90s with the classic Cowboys From Hell - caused my hair to reach out to others many's a time!
Therefore much of their fanbase are mature adults, often with families - and they continue to attract new fans despite being a defunct act.
