The performance of B.B. King, Mick Jagger, Buddy Guy, and other blues music icons at the White House in February 2012 for President and Mrs. Obama was a monumental occasion for a music form that had its beginnings in the “field hollers” of slaves picking cotton over 200 years ago. This playlist explores the many variations the blues has evolved into -- Black Gospel, Juke Joint, Boogie-Woogie, Delta Blues, Chicago Blues, West Coast Blues, British Blues, and more — during its journey from the cotton fields to the White House.
