This week’s eTown encore program showcases the famously raw and wonderful singer-songwriter Justin Townes Earle, performing some of his original songs from his latest album. We also welcome third-generation Texas musician Emily Gimble, a talented young pianist, vocalist, and songwriter who shares her own special brand of songs along with stories of growing up in one of the most famous American musical families. Nick also sits down for a conversation with one of the co-founders of the grassroots organization “500 Women Scientists” which promotes the importance of science in general while raising the profile of female scientists around the world.
