Raz Khandpur, Renan McFarland and Caleb Harmon make up Cool Serbia, a Brooklyn band who play feedback-heavy rock music in venues across New York City and its environs. They began in Austin in December 2010 as Boy’s Life, changed their name a year later, and moved to New York not long after that. I caught up with them in their studio last weekend and got them to chat about their new EP, their move and the state of recorded music.
