In the new music video for Lisbon musician Xinobi’s track “Strides,” things get weird in the best possible way. Directed by the Callner Brothers, Ben and Adam, who are usually seen crafting clever commercials, the clip swaps adland polish for a floating-fanny-pack fever dream.

It starts simply enough: two guys by a fountain encounter a pair of glowing, sentient fanny-packs filled with “muy bien” (translation: very good) stickers. Naturally, they start spreading good vibes (and possibly confusion) all over Lisbon. Soon, they’ve inspired a spontaneous dance congregation that looks like a street party with a philosophical subplot.

Of course, not everyone’s thrilled. The “anti-muy bien” crowd soon appears, frowning through the funk and protesting whatever’s happening. The Callners summarize the chaos neatly: “Is this about embracing different people and ideas, or just two dudes wearing fanny packs getting their 10,000 steps in?” Hard to say. Either way, it’s muy bien.
