Rapper-ish electro-pop-kinda group Suiyoubi No Campanella seem like the sort of music group that should be poised for a big mainstream breakout (recently signing to a major label helping fuel that vision), as they take a growing music trend (silliness and a lack of interest in genre borders mixed with honest emotion…see Tofubeats and Kyary Pamyu Pamyu for two examples, one far more known than the other but still) and package it with an extremely camera-ready leading singer. But who knows what the ever-dwindling crowd of people buying music will take too, and instead let’s focus on the now. “Diablo” is the highlight from the trio’s recently released “first EP,” and like “Momotaro” before it, it zips from hip-hop to dance-leaning segments, loaded with at times silly lyrics but also a sweet chorus (and that piano). Watch the video above.
