Problem: Post-punk:

During the initial punk era, a variety of entrepreneurs interested in local punk-influenced music scenes began founding independent record labels, including Rough Trade (founded by record shop owner Geoff Travis) and Factory (founded by Manchester-based television personality Tony Wilson). By 1977, groups began pointedly pursuing methods of releasing music independently , an idea disseminated in particular by the Buzzcocks' release of their Spiral Scratch EP on their own label as well as the self-released 1977 singles of Desperate Bicycles. These DIY imperatives would help form the production and distribution infrastructure of post-punk and the indie music scene that later blossomed in the mid-1980s.

Problem: Carnival:

The Carnival continued its evolution in small/unimportant towns out of view of the rulers. The result was the uninterrupted celebration of Carnival festivals in Barranquilla (see Barranquilla's Carnival) now recognized as one of the Masterpieces of the Oral and Intangible Heritage of Humanity. The Barranquilla Carnival includes several parades on Friday and Saturday nights beginning on 11 January and ending with a six-day non-stop festival, beginning the Wednesday prior to Ash Wednesday and ending Tuesday midnight. Other celebrations occur in villages along the lower Magdalena River in northern Colombia, and in Pasto, Narino (see Blacks and Whites' Carnival) in the south of the country. In the early 20th century, attempts to introduce Carnival in Bogota were rejected by the government. The Bogota Carnival was renewed in the 21st century.
