Kasai Allstars are a 25-piece musical collective based in Kinshasa, Democratic Republic of the Congo. The musicians originally come from five bands, all from the Kasai region, but originating from five different ethnic groups: the Songye, Lulua, Tetela, Luba, and Luntu. Some of these groups have endured conflicting relationships over the centuries, they each have their own culture, their own language and their own musical traditions, which were always thought to be incompatible until these musicians decided to pool their resources and form a "superband", at the instigation of Belgian producer Vincent Kenis
In 2008, they released an album on Crammed Discs entitled In the 7th Moon, the Chief Turned Into a Swimming Fish and Ate the Head of His Enemy by Magic, the third in the Congotronics series for the label (which also released material from the group Konono Nº1). The album was well received by Western music critics.
In November 2010, Crammed Discs released Tradi-Mods Vs. Rockers: Alternative Takes on Congotronics, a multi-artist album containing interpretations, covers and tributes to the music of Kasai Allstars, Konono Nº1 and other Congotronics bands, recorded by 26 indie rock and electronic musicians, including a.o. Deerhoof, Animal Collective, Andrew Bird, Juana Molina, Shackleton, Megafaun, Aksak Maboul, Mark Ernestus and others.
