3 Doors Down have stayed completely and utterly intact since 2000’s, 'Kryptonite,' while plenty of other rock bands have met a different fate: fighting, splitting, getting back together, splitting again. So, what’s the secret to the Escatawpa, Miss., quartet’s endurance? It’s simple: They stay friends.

"At this point, I've spent more time with them than I have with my own family,” guitarist Chris Henderson told LexGo.com. “I have seven brothers and one sister, but I spent more time with Brad and Todd — close time in buses, airplanes and hotels in different places around the world — than I have with anyone else on the planet. So I'm closer to these guys than anyone else on the planet. I know what they're thinking and they know what I'm thinking.

"That kind of thing, that kind of bond ... it's really indescribable."

What’s more, as the 3 Doors Down brotherhood grows, so do their fans. And, their fans are growing up, too.

"Some of the people were practically kids when they were listening to us 10 years ago. Now they're bringing their kids to the show,” he said. “We're seeing more families out there. That just shows the longevity of the band. That's one of the things we're most proud of — the fact that we've been able to continue to do this, because this is not really an easy gig to get."

3 Doors Down embark on a North American tour this fall with Theory of a Deadman and Pop Evil, and Henderson recently told Loudwire he’s pumped to tour with both acts. “They’re all good friends of ours,” he said. “We’ve never toured with Pop Evil, but we’ve done shows with them and we always talked about touring, but it never came around. This time, when Pop Evil’s name came up, we were like, 'Sounds like a good match for us.' Theory are good friends of ours, and I’ve known [frontman] Tyler [Connolly] for 15 years. I’ve always enjoyed hanging with him, and it’s going to be really fun.”
