A performance, in the performing arts, generally comprises an event in which a performer or group of performers present one or more works of art to an audience. Usually the performers participate in rehearsals beforehand. Afterwards audience members often applaud. After a performance, performance measurement sometimes occurs. Performance measurement is the process of collecting, analyzing and reporting information regarding the performance of an individual, group, organization, system or component.
The means of expressing appreciation can vary by culture. Chinese performers will clap with the audience at the end of a performance; the return applause signals "thank you" to the audience. In Japan, folk performing-arts performances commonly attract individuals who take photographs, sometimes getting up to the stage and within inches of performer's faces.
Sometimes the dividing line between performer and the audience may become blurred, as in the example of "participatory theatre" where audience members get involved in the production.
Performances is a live DVD that features previously unreleased footages of Selena during the Johnny Canales Show, a live coverage music television show, from the periods of 1993 to 1994.
The DVD comes in with two different styles, one being made of super jewel and another made of Amaray. The two contain the same track listings and features. The DVD movie features half of the movie of live performances while the other half includes a Selena special which is presented by Johnny Canales.
Selena Performances was originally named Johnny Canales presenta... Selena (English: Johnny Canales presents... Selena) and was going to be released during the fall of 2008. Due to new management for EMI Latin Records the DVD was postponed. The DVD was originally planned to be a DVD of various performances of Selena during the Johnny Canales Show from 1990 to 1994 but the record company complied for a DVD that included both various live performances and a special that would talk about Selena's legacy currently. The promotional poster, talks about an upcoming Television film based on Selena's death, similar to the Famous Crime Scene: Selena that aired on VH1. The television film will be produced by The Walt Disney Company set to be released in 2011. The upcoming Selena United States Stamp Collection and the upcoming Selena museum tour is also talked about on the promotional poster.
