Roots of David Coverdale

AC/DC are an Australian rock band formed in Sydney in 1973. Their music has been variously described as hard rock, blues rock and heavy metal, although the band calls it simply "rock and roll". They are cited as a formative influence on the new wave of British heavy metal bands. The band was inducted into the Rock and Roll Hall of Fame in 2003 and have sold over 200 million records worldwide, making them one of the best-selling artists of all time.

Robert Calvin Bland, known professionally as Bobby "Blue" Bland, was an American blues singer. Bland developed a sound that mixed gospel with the blues and R&B. He was described as "among the great storytellers of blues and soul music... [who] created tempestuous arias of love, betrayal and resignation, set against roiling, dramatic orchestrations, and left the listener drained but awed." The inspiration behind his unique style was a Detroit Preacher, CL Franklin, because Bland studied his sermons. He was sometimes referred to as the "Lion of the Blues" and as the "Sinatra of the Blues". His music was influenced by Nat King Cole.
