By now you may have heard of the intercontinental, surprise collaboration between Courtney Barnett and Kurt Vile, for an album called Lotta Sea Lice. The two singers have been mutual admirers for a while and kept bumping into one another at various festivals. Their guitar-based rock songs are laced with a shared sense of humor, and that was part of what got them creating music together. On this edition of All Songs Considered, Kurt and Courtney join host Bob Boilen in our Washington D.C. studios to talk about their mutual love for singers with guitars and a knack for writing songs that touch the heart, including cuts by The Sadies, John Prine, Gillian Welch, Tom Petty and Elliott Smith.
