Journalist Masha Gessen's new book 'The Brothers' is about Tamerlan and Dzhokhar Tsarnaev, the brothers behind the Boston Marathon bombing. She shares her reportage from Dzhokhar's trial as well as her travels to Dagestan, where she learned more about the Tsarnaevs' background. Also, April 7 marks the hundredth birthday of singer Billie Holiday, born in Philadelphia. Our jazz critic Kevin Whitehead has some thoughts on Holiday’s changing style, her influences, and singers she influenced.
