John Lee Hooker (August 22, 1917 – June 21, 2001) was a highly influential American singer, songwriter and guitarist. He developed a 'talking blues' style that became his trademark. Though similar to the early Delta blues, his music was often metrically free.
Joe Pass (1929-1994) was an American virtuoso jazz guitarist of Sicilian descent. He is generally considered to be one of the greatest jazz guitarists of the 20th century. His extensive use of walking basslines, melodic counterpoint during improvisation, use of a chord-melody style of playing and outstanding knowledge of chord inversions and progressions opened up new possibilities for the jazz guitar and had a profound influence on later guitarists.
