John Leslie "Wes" Montgomery (March 6, 1923 – June 15, 1968) was an American jazz guitarist. One of the most influential guitarists of the twentieth century, Montgomery was known for an unusual technique of plucking the strings with the side of his thumb and his extensive use of octaves, which gave him a distinctive sound.
Montgomery often worked with his brothers Buddy (Charles F.) and Monk (William H.) and with organist Melvin Rhyne. His recordings up to 1965 were oriented towards hard bop, soul jazz, and post bop, but around 1965 he began recording more pop-oriented instrumental albums that found mainstream success. His later guitar style influenced jazz fusion and smooth jazz.
