This Sunday, 311 is playing ACL Live. It’s been 25 years since a group of Omaha teens haphazardly smashed together elements of reggae, rap and rock to create a distinct sound that would rapidly propel them to the top of radio charts while earning them a rabid fan base. The group celebrates their silver anniversary with the lineup that made them famous still intact. Their 2014 release “Stereolithic” garnered little praise, but they have a new box set “Archive” that packages bonus tracks, B-sides and demos with a 60-page book of rare photos and memorabilia that should please longtime fans.

You have two days to still catch the show Sunday at 8 p.m. at ACL Live, but whether you make it there or not, you can still have a chance to win the “Archive” box set with our giveaway! Email the correct answer to the following trivia question to jstone@statesman.com with the subject line “311 Giveaway” by 5 p.m. Sunday before the show, and we’ll pick a random winner!

Q: The band draws their name from an Omaha police code for a crime. What is it?
