This week on American Routes, we’ll talk to folk-rocker, songwriter and guitarist Richard Thompson. An advocate for British lyric and music tradition in new settings with refashioned traditional songs and stories, Thompson evolved from playing in the seminal folk-rock band, Fairport Convention to his present day role as an in-demand guitarist and songwriter. Then we’ll visit with accordion-man Zachary Richard about growing up in French-speaking south Louisiana but needing to go to France and Quebec to realize the significance of the Cajun culture into which he was born. Richard’s recent “Le Fou” may be the first Americana record made largely in the French of his homeland: south Louisiana’s Cajun country.
