What makes an artist tick? Is there a craft that can be honed or is there something bigger than us that gives a creative their spark? These are the questions CBS News’ Senior Culture Correspondent Anthony Mason asks of some of the greatest artists alive today. With his new independent YouTube series Alchemy, he's inviting the audience into his apartment to hear in depth conversations about the creative process. The show debuted in May with icons Paul Simon, Hozier, Nile Rogers, Brittany Howard, and others, with more coming. Mason joined our own Brian Cosgrove in the WLIW-FM studio in July, sharing insights and stories.
