Blue Cheer was an American Psych-Blues band from UsefulNotes/SanFrancisco, active from the late [[TheSixties 1960s]] until 2009, when longtime member [[CoolOldGuy Dickie Peterson]] died of prostate cancer. Their first album, ''[[CanisLatinicus Vincebus Eruptum]]'', was a major influence on HeavyMetal music, with its thick guitar assaults.

!!Their work provides examples of:
* CanisLatinicus: ''Vincebus Eruptum'' is a nonexistent Latin phrase. [[labelnote:Explanation]]The closest use of the phrase in real life could be either "vinculis erupto", which translates to "bonds broken up", or "vinculis erumpti", which translates to "prison break" (which is oddly appropriate, given their cover of the prison song "Parchman Farm"). As an in-joke, if you type in "Vincebus Eruptum" as your input on the Latin to English setting on Google Translate, the phrase is translated as [[EasterEgg "Blue Cheer"]].[[/labelnote]]
* CoverVersion:
** Their rocking covers of Music/EddieCochran's "Summertime Blues" and Mose Allison's "Parchman Farm". Not to mention their cover of Music/TheRollingStones "Satisfaction".
** Blue Cheer's version of "Summertime Blues" was in turn covered by Music/{{Rush}}.
* LettingTheAirOutOfTheBand: Inverted with their cover of "Satisfaction", which slowly starts up then goes into the usual Cheer overdrive.
* HeavyMetal: A major influence on the genre, in fact, some consider them to be one of the very first heavy metal bands.
* RockTrio: During their first two albums and parts of the third.
* TropeMaker: Of Heavy Psych, a subgenre of PsychedelicRock, that relied on EpicRocking and thick guitar assaults. It served as a historical link between 60s rock and metal music.
