The H.O.S.T Alliance group (H.O.S.T.) operated from 2007 to 2012. The name of the rap group is formed from the initial letters of the words air, fire, water, and earth. The members of the group were engaged in rap activities separately until the union. The group's activities gradually ended due to the emergence of ideological and musical disagreements within the group, as well as the members' preference for individual creative paths and different projects. The group played a role in the formation and popularization of alternative music culture in Azerbaijan.
