Linea aspera

The linea aspera (Latin: rough line) is a ridge of roughened surface on the posterior surface of the femur, to which are attached muscles and intermuscular septum.

Its margins diverge above and below.

The linea aspera is a prominent longitudinal ridge or crest, on the middle third of the bone, presenting a medial and a lateral lip, and a narrow rough, intermediate line. It is an important insertion point for the adductors and the intermuscular septa that divides the thigh into three compartments. The tension generated by muscle attached to the bones is responsible for the formation of the ridges.

Linea Aspera (band)

Linea Aspera were a dark wave-minimal wave band formed in London, England that were active from 2011 to 2013. A musical duo, they were fronted by vocalist Zoè Zanias (known as Alison Lewis while in the band), with Ryan Ambridge on synthesizers; Zanias wrote the lyrics while Ambridge wrote the electronics, as well as mixing and producing the recordings.

Founded in November 2011, Linea Aspera were influenced by electronic bands from the 1980s. A reviewer reporting on a gig in January 2012 noted that their music sounded "very 80s", and that they had "sprung fully-formed" from the musical underground of East London. That month self-releasing an extended play cassette, titled Linea Aspera EP, it was described by the Burning Flame website as number one in their Top 20 EPs of 2012.

Signing to Dark Entries Records, the band's first album, Linea Aspera LP, was released on 25 September 2012. Brought out digitally and on vinyl by Dark Entries, a CD release was produced by the German company Genetic Records. Each LP was contained in a jacket sleeve designed by Dovile Shurpo and accompanied by an insert listing their song lyrics.
