Offspring and 311 just covered each other in the year of our lord 2018

In a sense, we have been waiting for this since yesterday, when Billboard broke the urgent news that SoCal mall-rock legends 311 and Offspring would be covering each other, an act of artistic cross-pollination performed in honor of the bands’ upcoming joint tour, which kicks off next week. But in another, more accurate sense, we have been waiting for this crossover since roughly 1995, when the two bands’ complementary styles of bratty skate-thrash and amber-colored reggae-thrash soared throughout the airwaves, inspiring all of middle-America to buy a pair of Oakleys and briefly try to skateboard.
Per the Billboard article, it was Offspring’s idea, and, as 311's Nick Hexum elaborates:
“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 (sic) 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.”
Today—after either one day of waiting or 23 years, depending on how you’re counting—they finally released the songs. We will hold them back no further. Let’s begin with the inciting incident, Offspring’s cover of “Down,” which, if you want to sing along, begins with the word “chyeaaaaaaaah”:
