Ashra (band)
Ashra is a project begun by Manuel Göttsching in 1976, initially to facilitate his solo career although other members were included later on. The band's name is an abbreviation of the name of Gottsching's previous band, Ash Ra Tempel. The name was changed as Gottsching's music became less psychedelic and more oriented towards electronica.
History
Ash Ra Tempel played their last concert in February 1973, their final album Starring Rosi was recorded later that year (featuring future Ashra member Harald Grosskopf). At the demise of Ash Ra Tempel, Göttsching remained musically inactive until 1975 when he released his debut solo album Inventions for Electric Guitar. This album introduced the effects he would later make use of in his work as Ashra, but in a much more basic form. Later that year Göttsching was commissioned to record a film soundtrack. The resulting album was released in 1993 as Le Berceau de Cristal under the Ash Ra Tempel name, despite the fact that none of the original members of that band feature. Instead, Gottsching was backed by former Agitation Free guitarist Lutz Ulbrich, who would go on to collaborate with Gottsching as Ashra.
Correlation and dependence
In statistics, dependence is any statistical relationship between two random variables or two sets of data. Correlation refers to any of a broad class of statistical relationships involving dependence, though it most in common usage often refers to the extent to which two variables have a linear relationship with each other. Familiar examples of dependent phenomena include the correlation between the physical statures of parents and their offspring, and the correlation between the demand for a product and its price.
Correlations are useful because they can indicate a predictive relationship that can be exploited in practice. For example, an electrical utility may produce less power on a mild day based on the correlation between electricity demand and weather. In this example there is a causal relationship, because extreme weather causes people to use more electricity for heating or cooling; however, statistical dependence is not sufficient to demonstrate the presence of such a causal relationship (i.e., correlation does not imply causation).
Correlations (album)
Correlations is the third studio album by German electronic music group Ashra, released in 1979. It is the first Ashra album to feature a full band; the first two albums under the name had actually been Manuel Göttsching solo albums.
The album features a cover designed by Hipgnosis.
In 2008, the album was reissued as a limited 5-CD box set under the title Correlations Complete. This release includes the original album, the previously released 3-CD set The Making Of and the previously unreleased original mix, titled Phantasus.
