Ethan Shanfeld Young the Giant frontman Sameer Gadhia has teamed with SiriusXM to launch the new podcast “Point of Origin,” which is “dedicated to amplifying voices of color from around the world while challenging the homogenous narrative in alternative and indie rock music.” Brittany Howard, former singer of Alabama Shakes, will appear as the podcast’s first guest to discuss her latest solo studio effort, “What Now.” Each episode of “Point of Origin,” which is available on the SiriusXM app, will explore the lives and careers of musicians of color and include a fully curated “life playlist” full of the guest’s favorite songs. The podcast stems from Gadhia’s radio show of the same name, which aired on SiriusXM’s Alt Nation.
