A world music fusion of African and Celtic traditions with electronic dance elements, Afro Celt Sound System rose to international acclaim in the late '90s. Spearheaded by British musician and producer Simon Emmerson, the revolving collective of musicians enjoyed success with a series of albums including 1999's Volume 2: Release and 2005's Volume 5: Anatomic. Following a hiatus, the group returned to touring in 2010 but split into two factions over a dispute regarding rights to the band's name. Emmerson claimed primary ownership of ACSS in 2016, releasing the comeback album The Source, followed two years later by Flight.
