“Sektor gaza” (Russian: Сектор газа) was a Russian rock band formed on 5 December 1987 in the city of Voronezh, Russia. Despite only semi-officially existing (due to obscene lyrics), the group remains popular in Russia today. The group name was taken from an eponymous industrial district of Voronezh (itself named for high levels of environmental contamination). Their music style could be defined as Russian punk, integrated with elements of different musical genres such as rock, rap, and Russian folk. On 4 July 2000, group leader Yuri “Hoy” Klinskih complained of strong pains in his stomach and the left side of his chest. He suffered heart failure shortly thereafter.
