Gawain (opera) Gawain is an opera with music by Harrison Birtwistle to a libretto by David Harsent. The story is based on the Middle English romance "Sir Gawain and the Green Knight". The opera was a commission from the Royal Opera House, London, where it was first performed on 30 May 1991. Rhian Samuel has published a detailed analysis of the opera. Birtwistle revised it in 1994, and the premiere of the revised version was given at the Royal Opera House on 20 April 1994.
Wotagei Wotagei or otagei (ヲタ芸 or オタ芸 ) refers to a type of dancing and cheering gestures performed by wota, fans of Japanese idol singers (and thus seen as Akiba-kei), involving jumping, clapping, arm-waving and chanting slogans. Wotagei is performed at concerts, or at events such as anime and manga conventions and meetings of idol fan groups, and it is thought to have developed from the ōendan, organised cheering squads common at sporting events in Japan. Wotagei is particularly associated with fans of Hello! Project and AKB48 idols, as well as fans of anime voice actresses, who often perform theme songs for the series in which they appear.
