“1 Corinthians 13 is set to the tone of ‘In a Sentimental Mood’ by John Coltrane, played on trombone by Matthew Hartnett. ‘In a Sentimental Mood’ sets the canvas for the message Matthew paints, using the color palette and scriptural context of 1st Corinthians Chapter 13. The production style is marked by Matthew Hartnett’s reimagining of the jazz song being sampled into and throughout the song.”
“In a Sentimental Mood” was composed by Duke Ellington (1935). Coltrane recorded it with Ellington in 1963.Matthew Hartnett is the founder of The Gumbo Jam, the group, and of the Gumbo Jam Session, the improvised event that gained its notoriety in New York and has since been copied around the world.
With 1Cor13 he brings an improviser's spirit to a sacred text: jazz tradition, modern sampling and spiritual depth in one release.
The group is The Gumbo Jam. The Session is the party it became known for.
A Gumbo Jam Session, New York
The Gumbo Jam Session is an improvised event that the group puts on. Matthew founded it in New York and brought it home to Houston. Every song is improvised, and singers, rappers, poets and horn players sit in, with guests from the bands of Lauryn Hill, Mariah Carey, Erykah Badu, Talib Kweli and Snoop Dogg.
It is optional. A session can be added to a concert as a segment, and it is a judgement-free room where the stage is the pot and everyone who sits in is an ingredient.
“Live music, pure souls, and VEGAN GUMBOOOO!! The vibes were phenomenal and I'll be back next Sunday. I adopted a new departure phrase, ‘Peace on purpose.’”
Gumbo Jam Session guest“Tonight was nothing short of amazing! @matthewhartnett is a musical genius.”
