The first florid trills of piano wash in, and Sech is here to celebrate reggaetón in its home. The scene: the light-soaked Biblioteca de la Autoridad del Canal de Panamá Roberto F. Chiari. Sech arrives with a book he places on the table. His blazer bears his name, the isthmus of Panama and its flag, and the likeness of Panamanian Yankee great Mariano Rivera and his jersey number, 42 (the namesake of Sech's most recent album). He approaches the mic for a silky version of "Playa" that, like the rest of his Tiny Desk set, is nearly entirely acoustic.
