Carín León is an old soul. There is no other way to account for the power of the emotion in his voice. His 16-piece band tests the limited space behind the Tiny Desk, but when the brass takes over to punctuate a performance, Leon's commanding presence shows why he's one of the best at what he does. Regional Mexican music is based upon song forms from another era, but León's lyrics add a new spin on heartbreak and love lost. This set opens with "Ese Vato No Te Queda," followed by two songs from the 2024 album Palabra De To's. Previously, León premiered "Primera Cita" for his Tiny Desk (home) concert, which became a major hit. That song "left a mark on our lives and completely shaped our careers," he shares. For good luck, León here premieres "Por la Suave," which was also written by Alejandro Lozano. "A poem that I love," León says.
