Garage rock
Among the numerous "rebellious" arts that emerged in the twentieth century as an opposition to everything mainstream there are probably a lot more non-mainstream music styles and genres as there are mainstream ones. The point is whether they are worth to be called 'alternative music' (in the most common sense of the word) or not. One of such rebellious genres of music is garage rock. Garage rock first appeared in the United States and Canada in 1960s. It is considered to be the major predecessor of punk rock and an important part of proto-punk. It is sometimes also called "garage punk". The name of the genre is understood from its name: it is basically music played in garages. The tradition was started by young musicians that had no money (or rather were not talented enough) to be recorded in professional recording studios and thus had to rehearse as well as record their music in their garages. The reason why such musicians played mainly in garages is because in a typical layout of an American or Canadian house the garage is the place where there is plenty of room (for drums, cables, amplifiers, cabinets, various instruments etc.) and nobody lives so that you won't bug anyone by playing loud all day long. Although many famous talented rock musicians (such bands as The Sonics, The Wailers etc.) started as garage rockers, a lot more of them remained unknown as, frankly speaking, their music was not much better than simply noise (although the concept was and still is seriously taken when people talk about lo-fi music.
