In 2005, a duo of Puerto Rican artists released their eponymously titled debut album "Calle 13." Their mix of reggaeton and rap took the Latinx music scene by storm and got them three Latin Grammy awards. In 2017, one half of that duo, René Juan Pérez Joglar—better known as Residente—released his first solo album. To find inspiration, he took a genealogical DNA test and traveled to every part of the world that showed up in the test, where he collaborated with local musicians. Now, Residente is working on his second solo album, which involves the brainwaves of worms. Maria Hinojosa sits down with Residente to dig into the mind of the man who has experimented with so many musical genres.
