Bantu is the name of a piece for four guitars by Andrew York. I have dicovered this piece on the CD Labyrinth by the Los Angeles Guitar Quartet.
Like in Rumba by Stepan Rak the guitars are also used as percussion instruments.
Andrew York has been a member of the LAGQ for many years. He has composed many pieces for guitar ensembles.
On the website of the LAGQ I have found the following text about Bantu:
Bantu, says Scott Tennant, “one of our favorites to play, is best described as a cross between African drumming rhythms and Dave Brubeck.”
I have found a number of youtube videos with guitar quartets and also bigger guitar ensembles that play Bantu. I have collected the best videos in my youtube playlist:
