Never too early to let some summer moods in. Kumachan Seal (solo project of a member of Casio Toruko Onsen AND Emerald Four) creates a dub-glazed dance number with “Ra Do Namin,” a breezy number heavy on vibe. Kumachan Seal avoids words in favor of using their voice as another instrument, lending the song a warmth even as parts of it burble off. Place it in the same lane as a project like Half Mile Bach Club, both channeling sounds apt for the coast and pushing them close to unnerving territory without going over. And it remains damn fun. Listen above.
