In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

The VinylDisc is a combination of a digital layer, either in CD or DVD format, and an analog layer, which is a vinyl record, developed by the German company Optimal Media Production. It consists of a silver layer containing CD or DVD and a black polyvinyl chloride layer (able to hold 3.5 minutes of audio on 33⅓ rpm) which can be played on a regular phonograph.
Examples of singles already released in the hybrid format are Paramore's "Misery Business", The Mars Volta's cover of "Candy and a Currant Bun" by Pink Floyd, and the 2017 album "Hyakki Echo" by Merzbow and Fightstar's "Deathcar" which reportedly had a limited run of 3000 copies.[1] A sample VinylDisc to promote this new format was given to visitors of the 2007 Popkomm, containing music by Jazzanova, where it was presented in September 2007.[citation needed]

The phonautograph is the earliest known device for recording sound. Previously, tracings had been obtained of the sound-producing vibratory motions of tuning forks and other objects by physical contact with them, but not of actual sound waves as they propagated through air or other mediums. Invented by Frenchman Édouard-Léon Scott de Martinville, it was patented on March 25, 1857. It transcribed sound waves as undulations or other deviations in a line traced on smoke-blackened paper or glass. Scott believed that future technology would allow the traces to be deciphered as a kind of "natural stenography". Intended as a laboratory instrument for the study of acoustics, it was used to visually study and measure the amplitude envelopes and waveforms of speech and other sounds or to determine the frequency of a given musical pitch by comparison with a simultaneously recorded reference frequency. It did not occur to anyone before the 1870s that the recordings, called phonautograms, contained enough information about the sound that they could be used to recreate it. Because the phonautogram tracing was an insubstantial two-dimensional line, direct physical playback was impossible in any case. However, several phonautograms recorded before 1861 were successfully converted and played as sound in 2008 by optically scanning them and using a computer to process the scans into digital audio files.
The LP (from long playing or long play) is an analog sound storage medium, specifically a phonograph record format characterized by a speed of 33+1⁄3 rpm, a 12- or 10-inch (30- or 25-cm) diameter, use of the "microgroove" groove specification, and a black vinyl (a copolymer of vinyl chloride acetate) composition disk. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire US record industry and, apart from a few relatively minor refinements and the important later addition of stereophonic sound in 1957, it remained the standard format for record albums during a period in popular music known as the "album era". LP was originally a trademark of Columbia and competed against the smaller 7-inch sized "45" or "single" format by RCA Victor, eventually ending up on top. Today in the vinyl revival era, a large majority of records are based on the LP format, and hence the LP name continues to be in use today to refer to new records.
Ribs (рёбра, translit. ryobra), also known as music on ribs (Музыка на рёбрах), jazz on bones (Джаз на костях), bones, bone music or roentgenizdat (рентгениздат, lit. X-ray publishing), are improvised gramophone recordings made from polyester X-ray films. Mostly made through the 1950s and 1960s, ribs were a black market method of smuggling in and distributing music that was banned from broadcast in the Soviet Union. Banned artists included emigre musicians, such as Pyotr Leshchenko and Alexander Vertinsky, and Western artists, such as Elvis, the Beatles, the Rolling Stones, the Beach Boys, Ella Fitzgerald and Chubby Checker.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
