Parchment is a thin material made from calfskin, sheepskin or goatskin, often split. Its most common use was as a material for writing on, for documents, notes, or the pages of a book, codex or manuscript. It is distinct from leather in that parchment is limed but not tanned; therefore, it is very reactive to changes in relative humidity and is not waterproof. Finer-quality parchment is called vellum.

Parchment was developed in Pergamon, from which name it is believed the word "parchment" evolved, under the patronage of either Eumenes I, who ruled 263–241 BC; or Eumenes II, who ruled 197–158), as a substitute for papyrus, which was temporarily not being exported from Alexandria, its only source.

Herodotus mentions writing on skins as common in his time, the 5th century BC; and in his Histories (v.58) he states that the Ionians of Asia Minor had been accustomed to give the name of skins (diphtherai) to books; this word was adapted by Hellenized Jews to describe scrolls. Parchment, however, derives its name from Pergamon, the city where it was perfected (via the Latin pergamenum and the French parchemin). In the 2nd century BC a great library was set up in Pergamon that rivalled the famous Library of Alexandria. As prices rose for papyrus and the reed used for making it was over-harvested towards local extinction in the two nomes of the Nile delta that produced it, Pergamon adapted by increasing use of parchment.

Blue Cheer was an American rock band that initially performed and recorded in the late 1960s and early 1970s and was sporadically active until 2009. Based in San Francisco, Blue Cheer played in a psychedelic blues-rock style, and is also credited as being pioneers of heavy metal (their cover of "Summertime Blues" is sometimes cited as the first in the genre), punk rock,stoner rock,doom metal,experimental rock, and grunge. According to Tim Hills in his book, The Many Lives of the Crystal Ballroom, "Blue Cheer was the epitome of San Francisco psychedelia." Jim Morrison of The Doors called the group "The single most powerful band I've ever seen."

The band is said to have been named after a street brand of LSD and promoted by renowned LSD chemist and former Grateful Dead patron, Owsley Stanley.

Blue Cheer came together in 1966. It was co-founded by Eric Albronda and Jerry Russell, music aficionados who wanted to become involved with the San Francisco music scene of the 1960s. Both moved with Dickie Peterson from Davis, California, to San Francisco. Peterson had previously been with the Davis-based band Andrew Staples & The Oxford Circle, as well as future Blue Cheer members Paul Whaley and Gary Lee Yoder. The original Blue Cheer personnel were singer/bassist Dickie Peterson, guitarist Leigh Stephens and Eric Albronda as drummer. Albronda was later replaced by Paul Whaley, who was joined by Dickie's brother Jerre Peterson (guitar), Vale Hamanaka (keyboards), and Jerry Whiting (vocals, harmonica). Albronda continued his association with Blue Cheer as a member of Blue Cheer management, as well as being the producer or co-producer of five Blue Cheer albums.
