Budaörs is a city in Pest county, Budapest metropolitan area, Hungary. The town has a large German-speaking minority who call it Wudersch. In Croatian, it is called Jerša, Erša and Vundeš (names by local Croat minority).

The town lies among the Buda and Csiki hills and the Tétény plateau in the Budaörs-basin.

The first settlements of the area date from 3500 BC. Excavations near the Hosszúrét creek resulted in findings from the Bronze age (1900 to 800 BC). Before the Romans, the Celtic Eraviscus tribe occupied the area for about 100 years. Several villas have been recovered from the Roman times around Kamaraerdő.

Little is known of the early history of the settlement after the Hungarian conquest. The name originates from the name of one of the Kabar tribes that joined the Hungarians.

The first written mention of Örs dates from 1236 when Béla IV, king of Hungary donated a church together with the St. Martin chapel to the Cistercians. Under the Turkish occupation during Ottoman rule the area was uninhabited and was resettled by Schwab peasants in the early 18th century by the countess Zsuzsanna Bercsényi.

Edda Művek is a highly successful Hungarian rock band formed in 1973 under the name "Griff". The word "művek" (works) symbolizes the band originally starting off its career in Miskolc, a typical Central European industrial city also dubbed as "Steel City"

Edda's catchy, melodic rock tunes and touching ballads primarily focus on the social and emotional life of youth. The band performs more than one hundred shows annually throughout Hungary and surrounding Hungarian communities around the Carpathian Basin. However, the energetic and inventive musicianship that EDDA's known for, is best reflected through their dynamic live performances.

The last member change occurred in 1997 with drummer, Hetényi Zoltán replacing Donászy Tibor. In 1998 the band released their first English language album, "Fire and Rain". Presently, the band releases original studio material every three to four years, while maintaining a vigorous tour schedule. The band regularly holds special concert events commemorating significant turning points of its career. The release of their classic, self-titled debut album in 1980 marked the official start of EDDA Művek as a professional musical outfit, hence the special Birthday Party events organized by the band every five years celebrate 1980 as the band’s true inception date. Occasionally, past members of EDDA’s classic line-up (1980-1984 era) also make guest appearances and perform alongside the band, an indication of singer Attila Pataky’s reconciliation with old band mates over the years
