On this episode, we’re heading north — not for a travelogue, exactly, but for a set of songs by Canadian artists who have left their mark on pop, rock, folk, jazz, country, and just about every corner of popular music. Canada has given us teen idols, folk poets, arena rockers, new wave voices, singer-songwriters, and a few songs that feel almost like unofficial national souvenirs. We’ll move from Paul Anka and The Guess Who to Joni Mitchell, Gordon Lightfoot, Rush, k.d. lang, The Tragically Hip, and more.
