On a steaming day in summer 2006, Michal Dvořáček, a singer and composer and Slávek Hamaďák, a producer, were pondering some recordings by a rock group ENTER in a rented appartment in Hradec Králové, when the doorbell rung three times to interrupt the session. Michal Dvořáček opened the door, but nobody was there. "I gotta run down to get it," he shouted and slammed the door shut. Meanwhile, out of sheer curiosity Slávek browsed through the music files on Michal's computer and discovered several pieces of music sung in Swahili.
