It's a NEW band but they are still rooted in the old band and perform songs from all eras. Stu picked the name and he's retired from the band now so that name has a totally different meaning to the three members now. They are and will always be This Town Needs Guns. They just choose to simply use TTNG instead of the full name. And 9 years ago when they named it, people weren't walking into schools and gunning down kids either.
Kinda weird to change it the day before the new album drops. Also, hopefully there aren't any bonus tracks on that Japanese version because I hate when bands do that.
