Koinonia was a band birthed from the fusion in jazz music, which occurred in the 1970s and 1980s, giving to a new, more electrified and diverse genre called jazz-funk. Other notable pioneers in this genre were: The Crusaders, Weather Report, Herbie Hancock, Alphonse Mouzon, Chick Corea, Lee Ritenour, Azymuth, Eumir Deodato, Jeff Lorber, and Seawind.
Though less known in the United States, Koinonia established themselves as a huge sensation in Scandinavia and Western Europe, performing to sell-out crowds from 1982 to 1991 in Norway, Denmark, The Netherlands, Sweden, Finland, Germany, Switzerland and France. Their Latin-infused rhythms and upbeat melodies gave them a distinct and cultured sound. Taken from a Greek word used in the Bible to mean "intimate fellowship" Koinonia was notably one of the first Christian, though primarily instrumental, jazz bands.
The original founding members of the band in 1980 were: (leader) classically trained guitarist, Abraham Laboriel on electric bass guitar, child-prodigy drummer Bill Maxwell, Dean Parks on guitar, Alex Acuña on percussion and drums, John Phillips on woodwinds, Hadley Hockensmith on guitar, and Harlan Rogers on keyboards. In 1981 the saxophone/clarinet and flute virtuoso Justo Almario replaced John Phillips. Dean Parks also left at that time, because he preferred not to travel. Chester Thompson joined one tour in Europe in 1987, replacing Alex Acuña, but Thompson was never an official member of the band. In 1988, Lou Pardini joined the band on keyboards and vocals. Koinonia disbanded in 1991.
Each member has gone on to be successful individual and/or studio and session musicians working with many giants of the music industry. Hadley Hockensmith has been Neil Diamond's guitarist for 25 years. Dean Parks, best known for his contributions with Steely Dan and Michael Jackson, is still one of the top studio guitarists in Los Angeles. And Alex Acuña is one of the major LA studio film percussionists and tours with his own band. Harlan Rogers has retired from music and lives in Nashville. Lou Pardini has recorded several of his own albums, composing a Grammy-award winning song for Smokey Robinson as well. John Phillips has been out of contact.
As of 2014 Abraham Laboriel, Justo Almario, Bill Maxwell, with the addition of long-time arranger/composer/sessionman, Greg Mathieson, make up the jazz-fusion quartet known as Open Hands, based in Los Angeles.
It should also be noted that early on, Koinonia set a high standard for excellence in music for the Christian Music/Gospel Music genres which was still, at that time, relatively young to the commercial music scene.
