Sarah Jarosz is hardly a just a “young Youtuber”. She’s a multiple Grammy winning musician who released her first album (which also led to her first Grammy nom) in 2009. She’s an acclaimed songwriter, singer, and instrumentalist who is frequently featured on “Live from Here” with Chris Theile. She deserves considerably more respect than you seem to be giving her.
