What defines a NWOTM band?

So what defines a NWOTM band?

People may point to bands such as Lazarus A.D., Bonded By Blood, or Gama Bomb as examples, but to be considered a NWOTM band, does it totally rely on how recent a band was formed?

If a new thrash band with a brand-spankin'-new record is thought of as a NWOTM band, would it sway people's thinking of that same band if there is one old-school metal vet within the ranks?

Consider Steve "Zetro" Souza's new band Hatriot.

From what I can tell as of this posting, the band is made up of four younger musicians, and Zetro - former lead vocalist of the classic thrash group Exodus.

Would most people not consider Hatriot a NWOTM band simply because Zetro is in the group? Classic thrash will always come to mind when Zetro's name is mentioned, making it easier to lump them in with the old-school bands instead of with bands like Hatchet or Evile.

However, it's a no-brainer that if Steve had nothing to do with Hatriot, they would most definitely be considered part of the NWOTM.

The same could be said about the band Pasadena Napalm Division. With members from D.R.I. and dead horse, it's hard not to place them amongst old-school royalty, because these guys are freaking old-school royalty. However, the band itself is not. P.N.D. is relatively new, placing the band in the era of new school.

Does it really matter? No.

But it is interesting that the age of the band or who is in it can alter people's perceptions.
