3OH!3So you’re probably wondering, what does 3OH!3 stand for? The answer you ask? The name refers to the 303 area code of Boulder, Colorado where 3OH!3 members Sean and Nathaniel hale. Now let me tell you something, these guys are big and they know they’re big. Why? You know your big when bus loads of kids are lined up outside 10 hours before your show and every other radio station has your song in heavy rotation. With all that being said, 3OH!3 were actually very humble and cool guys. See for yourself.
