For a form built around the most aggressively insistent kick pattern in music, reggaeton has mellowed out a lot in recent years, sinking lower into its figurative Jacuzzi. Leave it to this Montreal-via-Honduras alt-sensation to shut off the gentle jets of synthy-R&B and Eighties fetishism beloved by the genre’s male stars and instead set that shit to boil. A punchily melodic rapper in an era of sodden, simpering singers, Isabella Lovestory favors neck-snapping neo-perreo beats for her salaciously vulgar lyrics. And with songs dabbling in industrial metal and electroclash textures, that aggressive insistence gives way to pure, exhilarating hostility. Latin electronic producer Kamixlo opens.
