Black Hour, often stylized as Blackhour, is a Pakistani progressive rock band from Islamabad, founded in 2007 by guitarist Hashim Mehmood. After several lineup changes in its early years, the band settled on four members for more than a decade: Hashim Mehmood, drummer Daim Mehmood, bassist Salman Afzal and lead vocalist Tayyab Rehman. Black Hour has consistently incorporated progressive, folk, classical, and alternative influences into its compositions, as well as strong influences from heavy metal, especially in their early works.
