This week, Bill and Brian go sans guest to talk about U2's super-massive-megadon hit The Joshua Tree (1987, Island). Recorded after the band had spent years touring the US, alternately falling in love with its ideals and becoming outspoken critics of its international policies, and wanting to create something bigger and better than anything they had done before, U2 released this album to massive sales and critical praise. Brian and Bill talk about their personal connections with the music, how the album got made, and a track by track analysis of each song. Along the way, we discuss religion and secularism, Euler's number, how addiction has touched our lives, the legality of immigration, how music can spur community in the face of tragedy, and more!
