The Offspring have shared a cover of 311’s “Down” and 311 have covered “Self-Esteem.” You can hear the new renditions on Spotify or Apple Music. 311’s Nick Hexum talked to Billboard about how the idea came together:

It was the Offspring’s idea, and a great idea. They said, ‘We had the idea to cover your song, and we’ve done it,’ and I was like, ‘Wow! I have to hear this,’ ’cause it’s such a signature song. Were they going to cover it faithfully or rework it?’ They reworked it just enough; There’s punk to it, and Dexter (Holland) actually does a killer job of rapping SA (Martinez)’s parts in more of a punk rock style, with fast drums. We were so blown away, It was so my fun to hear that. So we returned the favor and reggaefied (‘Self Esteem’), which is probably my favorite song of theirs. It’ll be a lot of fun to give the fans new versions of these songs they love so much.
