A Spanish Show of Strength

Today is expected to be a national day of protest for immigrant rights. Mexican-American singer-songwriter Lila Downs stops by to discuss why she feels the immigration debate is so critical, and also weigh in the controversy surrounding the new Spanish version of the "Star Spangled Banner." Also: The firm Rafael Viñoly Architects has designed some of the world's most prestigious concert halls, from Philadelphia's Kimmel Center to Jazz at Lincoln Center theater to the Tokyo International Forum, a performing-arts and convention center. It's perhaps not surprising then that he almost pursued a career as a concert pianist. Today, "starchitect" Viñoly discusses the music that inspires his designs. Finally, a live performance by the band Hem.
