Plan B kicks things into overdrive with these dense, blistering creations. "Fronteo" piles Dutch house synths onto dembow drums, and "Pa'l Piso" stacks laser blasts and ominous ambience high above the rattling drums. The Puerto Rican pair flies circles around these reggaeton skyscrapers, abrasive voices chanting darkly and occasionally harmonizing amid lyrics about love, sex and—inevitably—heartbreak. On the lighter "Mi Vecinita," they sweetly pine for a dancehall-loving girl-next-door, but the sparse "Zapatito Roto" cooly says goodbye when a similar muse proves too much to handle.
