Beirut's Zach Condon is a magpie for sounds, collecting left-behind instruments and equipment from around the world. Condon can't explain what drove him from his hometown in New Mexico or his studio in Berlin to record Beirut's new album, Gallipoli in rural Italy, but he's the first to own up to "reading too many Tin Tin books" and having a childhood obsession with Indiana Jones. From halfway around the world, Condon, in this conversation, walked All Songs Considered's Bob Boilen through the experience that inspired Gallipoli's title track.
