Acid jazz is a musical genre that combines elements of jazz, funk and hip-hop, particularly looped beats. It developed in the UK over the 1980s and 1990s and could be seen as tacking the sound of jazz-funk onto electronic dance: jazz-funk musicians such as Roy Ayers, Donald Byrd and Grant Green are often credited as forerunners of acid jazz. Acid jazz has also experienced minor influences from soul, house, and disco.

While acid jazz often contains various types of electronic composition (sometimes including sampling or live DJ cutting and scratching), it is just as likely to be played live by musicians, who often showcase jazz interpretation as part of their performance. The compositions of groups such as Jamiroquai, Galliano, Urban Species, The Brand New Heavies and Incognito often feature chord structures usually associated with jazz music.

The acid jazz "movement" is also seen as a revival of jazz-funk or jazz fusion or soul jazz by leading DJs such as Norman Jay or Gilles Peterson or Patrick Forge, also known as "rare groove crate diggers" or "Cataroos".

John Leslie "Wes" Montgomery (March 6, 1923 – June 15, 1968) was an American jazz guitarist. He is widely considered one of the major jazz guitarists, emerging after such seminal figures as Django Reinhardt and Charlie Christian and influencing countless others, including Pat Martino, George Benson, Russell Malone, Emily Remler, Kenny Burrell, Pat Metheny, Steve Howe, and Jimi Hendrix.

Montgomery was born in Indianapolis, Indiana. According to NPR Jazz Profiles "The Life and Music Of Wes Montgomery," the nickname "Wes" was a child's abbreviation of his middle name, Leslie. He came from a musical family; his brothers, Monk (string bass and electric bass) and Buddy (vibraphone and piano), were jazz performers. The brothers released a number of albums together as the Montgomery Brothers. Although he was not skilled at reading music, he could learn complex melodies and riffs by ear. Montgomery started learning the six string guitar at the relatively late age of 20 by listening to and learning the recordings of his idol, guitarist Charlie Christian, however he had played a four string tenor guitar since age twelve. He was known for his ability to play Christian's solos note for note and was hired by Lionel Hampton for this ability.
