Reverb effect in the context of Sheet metal

Psychedelia usually refers to a style or aesthetic that is resembled in the psychedelic subculture of the 1960s and the psychedelic experience produced by certain psychoactive substances. This includes psychedelic art, psychedelic music and style of dress during that era. This was primarily generated by people who used psychedelic drugs such as LSD, mescaline (found in peyote) and psilocybin (found in magic mushrooms) and also non-users who were participants and aficionados of this subculture. Psychedelic art and music typically recreate or reflect the experience of altered consciousness. Psychedelic art uses highly distorted, surreal visuals, bright colors and full spectrums and animation (including cartoons) to evoke, convey, or enhance the psychedelic experience.

Psychedelic music uses distorted electric guitar, Indian music elements such as the sitar and tabla, electronic effects, sound effects and reverb, and elaborate studio effects, such as playing tapes backwards or panning the music from one side to another.

Dub is a musical style that grew out of reggae in the late 1960s and early 1970s. It is commonly considered a subgenre of reggae, though it has developed to extend beyond that style. Generally, dub consists of remixes of existing recordings created by significantly manipulating the original, usually through the removal of vocal parts, emphasis of the rhythm section (the stripped-down drum-and-bass track is sometimes referred to as a riddim), the application of studio effects such as echo and reverb, and the occasional dubbing of vocal or instrumental snippets from the original version or other works.

Dub was pioneered by recording engineers and producers such as Osbourne "King Tubby" Ruddock, Hopeton "Scientist" Brown, Lee "Scratch" Perry, Errol Thompson and others beginning in the late 1960s. Augustus Pablo, who collaborated with many of these producers, is credited with bringing the distinct-sounding melodica to dub, and is also among the pioneers and creators of the genre. Similar experiments with recordings at the mixing desk outside the dancehall scene were also done by producers Clive Chin and Herman Chin Loy. These producers, especially Ruddock and Perry, looked upon the mixing console as an instrument, manipulating tracks to come up with something new and different. The Roland Space Echo was widely used by dub producers in the 1970s to produce echo and delay effects.

An effects unit, effects processor, or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.

Common effects include distortion/overdrive, often used with electric guitar in electric blues and rock music; dynamic effects such as volume pedals and compressors, which affect loudness; filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as chorus, flangers and phasers; pitch effects such as pitch shifters; and time effects, such as reverb and delay, which create echoing sounds and emulate the sound of different spaces.

"Heartbreak Hotel" is a song recorded by the American singer Elvis Presley. It was released as a single on January 27, 1956, Presley's first on his new record label RCA Victor. It was written by Mae Boren Axton and Tommy Durden, with credit being given also to Presley. A newspaper article about the suicide of a lonely man who jumped from a hotel window inspired the song. Axton presented the song to Presley in November 1955 at a country music convention in Nashville. Presley recorded it on January 10, 1956, in a session with his band, the Blue Moon Boys, the guitarist Chet Atkins and the pianist Floyd Cramer. "Heartbreak Hotel" comprises an eight-bar blues progression, with heavy reverberation throughout the track, to imitate the character of Presley's Sun recordings.

The single topped the Billboard Top 100 for seven weeks, Cashbox's Pop singles chart for six weeks, and the Country and Western chart for seventeen weeks as well as reaching No. 3 on the R&B chart, becoming Presley's first million-seller, and one of the best-selling singles of 1956. "Heartbreak Hotel" achieved unheard of feats as it reached the top 5 of Country and Western, Pop, and Rhythm 'n' Blues charts simultaneously. It was eventually certified double platinum by the Recording Industry Association of America. Presley had first performed "Heartbreak Hotel" during a live show in December 1955 during a tour of the Louisiana Hayride; it gained popularity after his appearance on Stage Show in March 1956. It became a staple of Presley's repertoire in live appearances, last performed by him on May 29, 1977, at the Civic Center in Baltimore.
