American Routes belts it out in celebration of big voices. We’ll sample three from across the musical board: the eerie smoothness of Little Jimmie Scott, an 89-year-old jazz singer who’s recently been rediscovered; the crooning of country star Ray Price; and the gritty shout of Chicago blueswoman Koko Taylor.

After Halloween celebrations die down and All Saints meditations arrive, we settle back with the mellow music and words of our guest Lazy Lester: a hardworking bluesman from Louisiana’s provincial capitol of Baton Rouge. Then a tour of the world of African and African-American music from Morocco to Brooklyn with jazz pianist Randy Weston.

This American Routes focuses on Jewish, Arab-American, Middle Eastern and Islamic influences on African-American music and culture. Jerry Leiber and Mike Stoller talk about how “two young Jewish guys” from the East Coast wrote some of our most memorable songs, like “Hound Dog,” “Yakety Yak” and “I’m a Woman.” Plus: music portraying Old Testament tales in gospel and reggae; Middle Eastern images in jazz and pop; and the impact of Islam on the blues. Also, Atlantic Records founder and Turkish ambassador’s son Ahmet Ertegun looks back on over a half-century producing blues, jazz, R&B, soul and rock.
