The Punks: The Punks were an American proto-punk band from Waterford, Michigan near Detroit, who were active from 1973-1977.  They specialized in a hard-driving, sometimes thrashing sound that anticipated much mid-to-late 1970s punk rock and 1980s hardcore.  The group came out of the last vestiges of the Detroit rock scene that produced bands such as MC5, Iggy and the Stooges, and Death, and with these acts they formed a musical bridge between the garage rock bands of the 1960s and the later punk movement that emerged in New York and London during the mid-1970s.  In 1977 they changed their name to the End and moved to New York with hopes of making their mark in the burgeoning punk rock scene there, but were unsuccessful, and broke up shortly thereafter.  Though relatively unknown outside of Detroit and New York in their day, they have more recently garnered the interest and accolades of underground rock enthusiasts who consider them to be pioneers in the prototypical development of punk rock.  Parts of their song "My Time's Comin'" were used in the soundtrack of two March 2016 episodes of the television series, "Vinyl", co-created the Rolling Stones’ Mick Jagger and director Martin Scorsese.

The Litter were one of the protopunk bands to emerge from the scene in 1966.  Their heavily distorted guitar amplifiers played a high volumes became the "signature sound" for many punk bands that emerged much later.  A punk rock scene started to coalesce in the mid-late 1970s around Jay's Longhorn Bar and Oar Folkjokeopus record store.  The first recognized punk rock band from Minnesota was The Suicide Commandos, who formed in 1975.  Their first 7" EP was released in 1976.

Brisbane punk rock: Brisbane punk rock had its main impact between 1975 and 1984 as part of the overall punk rock scene in Australia.  According to rock music historian, Ian McFarlane, the Queensland capital provided "some of the most anarchistic bands" of that era whilst it was "arguably the most conservative city" in the country.  The development of the local punk movement differed from other cities because of its relative geographic isolation from other similar trends.  The Brisbane scene also received a greater scrutiny by local police where early punk bands formed as "an obvious backlash to an oppressed society".  This generated antagonistic and individualistic groups or "snot" driven punk bands.
