Industry refers to the production of an economic good or service within an economy.There are four key industrial economic sectors: the primary sector, largely raw material extraction industries such as mining and farming; the secondary sector, involving refining, construction, and manufacturing; the tertiary sector, which deals with services (such as law and medicine) and distribution of manufactured goods; and the quaternary sector, a relatively new type of knowledge industry focusing on technological research, design and development such as computer programming, and biochemistry. A fifth, quinary, sector has been proposed encompassing nonprofit activities. The economy is also broadly separated into public sector and private sector, with industry generally categorized as private. Industries are also any business or manufacturing. Industries can be classified on the basis of raw materials,size and ownership.
Industrial music is a style of experimental music that draws on transgressive and provocative themes. The term was coined in the mid-1970s with the founding of Industrial Records by the band Throbbing Gristle, and the creation of the slogan "industrial music for industrial people". In general, the style is harsh and challenging. Allmusic defines industrial as the "most abrasive and aggressive fusion of rock and electronic music"; "initially a blend of avant-garde electronics experiments (tape music, musique concrète, white noise, synthesizers, sequencers, etc.) and punk provocation".
