“Do Do Do” delivers fun, sure, but the latest single from Lucky Kilimanjaro also allows a little more doubt to creep in around the edges. Perhaps it has just been the recent feel-good-ery of stuff like “House,” but “Do Do Do” comes off as slightly less celebratory, despite still having plenty of pop going for it. That’s mostly because the project leaves a little more space around all the synth springs during the verses, giving this one a slightly more melancholy vibe. That’s until the handclaps come in and the vocals shoot up a level before a more familiar gobstopper of a hook, delivering the sugary energy. Listen above.
