Scan the credits of your favorite Latin pop songs, and you might just find the names Mau and Ricky. These songwriters-for-hire have penned hits in a dizzying range of styles, but the duo apparently saved their most passionate tunes for the sweeping Arte. You’ll find a handful of breezy moments like “Empiezo a Caer,” a lilting flirtation with folk. But the brothers really shine on slow-burn epics like “Para Olividarte,” an orchestral ballad that builds patiently toward an ecstatic, choir-driven climax.
