Pangaea was a supercontinent which connected all the landmasses, during the late Paleozoic and early Mesozoic eras. Like a puzzle whose pieces you can still see today—Africa fitting into South America, Greenland tucking back into Canada—it assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago, all according to livescience.com. The plates, and us on them, are still moving today, because of giant molten waves in the earth’s core, generated by convection currents. The good news is, Pangea wasn’t the first supercontinent in our 4.5 billion year history, and it won’t be the last, according to geologic predictions that say we’ll keep bumping our continental shelves into each other as long as the old home orb survives. Which is how today's show came about—cleaning and rearranging my CD shelves, I thought about how music truly does bring us all together, despite the shelf breaks of geography, language, instrumentation, or genre. Today, on ear to ear—continental shelves collide! Hermeto Pascoal, Laurel MacDonald, Terra Sul, Aziz Sahmaoui, Amy Sacko, Carlos "Patato" Valdes, more.
