So far over the course of this series, we've examined the madness and socio-political movements that made the Rolling Stones' 1972 North American tour a singular moment in pop culture. But very little attention has been paid to the music — especially the album that the Stones were on the road to promote: their moody double disc epic 'Exile on Main St.' To remedy this, host Jordan Runtagh and executive producer/co-composer Noel Brown sit down with legendary Georgia-based record maker David Barbe, a veteran of the band Sugar (with Hüsker Dü's Bob Mould) and the producer of albums from the likes of Drive-By Truckers and Son Volt. Together they throw down about all things Stones and discuss why the sound and style of 'Exile' continues to endure.
