The word comes from Stockholm Jazz Festival spokeswoman Liisa Tolonen, who said Hill’s representatives notified the festival Tuesday that the former Fugees singer was canceling all her summer Euro engagements.

Festivals affected include the Heineken Ejekt Festival in Athens, Greece, where Hill was scheduled to perform on June 19. Hill was also scheduled to appear at Munich’s Tollwood Festival June 29; Les Ardentes Festival in Liege, Belgium July 7; Montreux Jazz Festival July 11 and the Stockholm Jazz Festival July 18.

Other than citing health reasons for nixing the dates, Hill’s representatives did not offer any additional details.
