Eddie Lang was an American musician who is credited as the father of jazz guitar. During the 1920s, he gave the guitar a prominence it previously lacked as a solo instrument, as part of a band or orchestra, and as accompaniment for vocalists. He recorded duets with guitarists Lonnie Johnson and Carl Kress and jazz violinist Joe Venuti, and played rhythm guitar in the Paul Whiteman Orchestra and was the favoured accompanist of Bing Crosby.

Alonzo "Lonnie" Johnson was an American blues and jazz singer, guitarist, violinist and songwriter. He was a pioneer of jazz guitar and jazz violin and is recognized as the first to play an electrically amplified violin.
