Chemical substance

A chemical substance is a form of matter that has constant chemical composition and characteristic properties. It cannot be separated into components by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be chemical elements, chemical compounds, ions or alloys.

Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, in practice, no substance is entirely pure, and chemical purity is specified according to the intended use of the chemical.

Chemical substances exist as solids, liquids, gases or plasma, and may change between these phases of matter with changes in temperature or pressure. Chemical reactions convert one chemical substance into another.

Chemical (Joseph Arthur song)

"Chemical" is the first single from Joseph Arthur's second studio album Come to Where I'm From. The single was released in the UK and Australia on June 26, 2000 via Real World Records and Virgin Records. The single is long out of print and is now hard to find. Joseph very rarely played "Chemical" live--the first known version was in New York City in March 1998. A music video was produced for the song, directed by Anton Corbijn (however, the video does not appear on the Directors Label DVD The Work of Director Anton Corbijn). The video features Joseph as two characters: the first as himself, playing his guitar and singing the song, and the other as a man clad in black with a fake moustache and temporary tattoos. Joseph's friend Valdet builds a sculpture behind Joseph through the video.

Underground (The Electric Prunes album)

Underground is the second studio album by the American garage rock band, The Electric Prunes, and was released in 1967 on Reprise Records. It would be the final album of any materialized input by band members until the 1969 "New Improved" Electric Prunes were formed. The album was a moderate chart hit, but, without a hit-ready single, the band could not repeat their past success.

Background

The album, Underground, brought changes to the band once recording began. Limited lyrical input plagued the band's creative process on their debut. Only one track, composed by Mark Tulin and James Lowe, called "Lovin'" was included on their first album. This changed with this album because Dave Hassinger, the group's producer, was not as active in the sessions resulting in nine of the 12 tracks becoming the band's own material. With so much more musical freedom, the band could mold their music into their own image. The final products were a more direct and cohesive set of songs that reflected the band's own design.
