This week we interview Alejandro Madrid, an award-winning Cornell University musicologist who specializes in music and expressive culture from Latin America and Latinxs in the United States. He has authored more than a half dozen books, including his latest, Tania Léon’s Stride. A Polyrhythmic Life, published by the University of Illinois Press in December 2021. Tania Léon, now in her late 70s, is a sought-after composer, conductor, educator, and tireless advocate for the arts. Last year she was awarded a Pulitzer Prize for her composition, Stride, Léon’s orchestral tribute to the 19^th Amendment that granted women the right to vote. Alejandro Madrid was interviewed, online via Zoom on February 9, 2022, by fellow biographer and BIO member Sonja Williams.
