Q:Information:  - Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music. "Traditional folk music" has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles.  - The British Broadcasting Corporation (BBC) is a British public service broadcaster.

Initially termed "progressive pop", the style was an outgrowth of psychedelic bands who abandoned standard pop traditions in favour of instrumentation and compositional techniques more frequently associated with jazz, folk or classical music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening, not dancing.  - The V Shows is a live album/DVD recorded at the London Astoria by rock band Mostly Autumn. It was recorded on the tour supporting their 2003 release "Passengers". The DVD for this show was also included in their 2005 DVD release "Pink Floyd Revisited". Also, this is the first Mostly Autumn release to feature drummer Andrew Jennings.  - Pink Floyd were an English rock band formed in London. They achieved international acclaim with their progressive and psychedelic music. Distinguished by their use of philosophical lyrics, sonic experimentation, extended compositions and elaborate live shows, they are one of the most commercially successful and influential groups in the history of popular music.  - Hard rock is a loosely defined subgenre of rock music that began in the mid-1960s, with the garage, psychedelic and blues rock movements. It is typified by a heavy use of aggressive vocals, distorted electric guitars, bass guitar, drums, and often accompanied with pianos and keyboards.  - Psychedelic music (sometimes psychedelia) covers a range of popular music styles and genres influenced by the 1960s psychedelic culture, a subculture of people who used psychedelic drugs such as LSD, psilocybin mushrooms, mescaline and DMT to experience visual and auditory hallucinations, synesthesia and altered states of consciousness. Psychedelic music attempted to replicate the hallucinogenic experience of using these drugs or enhance the experience of using them. Psychedelic music emerged during the mid-1960s among folk rock and blues rock bands in the United States and Britain.  - The London Astoria was a music venue, located at 157 Charing Cross Road, in London, England. It had been leased and run by Festival Republic since 2000. It was closed on 15 January 2009 and has since been demolished.
