ZZ Top is "Goin' 50"

The band ZZ Top is marking 50 years together, with a new remastered collection of their greatest hits, “Goin’ 50.” Jim Axlerod talks with guitarist Billy Gibbons, bassist Dusty Hill, and drummer Frank Beard (the one without a beard) who are still working hard to make their pedal-to-the-metal, bluesy country rock seem so easy.
