Mor ve ötesi (literally Purple and Beyond; a play on the word morötesi, meaning ultraviolet) is a Turkish alternative rock band from Istanbul. Its four current members are Harun Tekin (vocals and rhythm guitar), Kerem Kabadayı (drums), Burak Güven (bass) and Kerem Özyeğen (lead guitar). Former members include Alper Tekin (no relation to Harun) and Derin Esmer. The band achieved mainstream success with the release of the album Dünya Yalan Söylüyor. In 2008, the band represented Turkey in the Eurovision Song Contest in Belgrade with the song "Deli" (Insane).
A main attraction in the Turkish music scene, mor ve ötesi followed a very rough path and had their breakthrough with their fourth album “Dünya Yalan Söylüyor” in 2004. The album sold over 300.000 copies and changed the way rock was perceived by the Turkish music industry. The hundreds of live performances they’ve had include several tours in Europe and the US. The band celebrated their 20th anniversary in 2016 with two special CD box-sets containing all of their published work. An inspiration to many bands and the voice of a generation, mor ve ötesi is a top-notch band defining the direction that Turkish rock is headed in.
