Rest in Peace Koko Taylor.
The legendary Queen of the Blues Koko Taylor died Wednesday afternoon at Northwestern Memorial Hospital while recovering from a surgery to repair gastrointestinal bleeding. She dies at 80. My condolences to the family, relative and friends of Koko Taylor.

A brief info of Koko Taylor from wikipedia;

Born in Shelby County, Tennessee, Taylor left Memphis for Chicago, Illinois in 1952 with her husband, truck driver Robert "Pops" Taylor. In the late 1950s she began singing in Chicago blues clubs. She was spotted by Willie Dixon in 1962, and this led to wider performances and her first recording contract. In 1965, Taylor was signed by Chess Records, for which her single "Wang Dang Doodle" (written by Dixon, and a hit for Howlin' Wolf five years earlier) became a major hit, reaching number four on the R&B charts in 1966, and selling a million copies. Taylor recorded many versions of this Dixon-penned song over the past few decades and has added more material, both original and covers, but never repeated that initial chart success.
