Polish music group founded in 1984 by Mirosław "Zacier" Jędras. The name Zacier was secondarily expanded as an abbreviation for: Association of Suffering and Enthusiastic Artists (Zrzeszenie Artystów Cierpiących i Entuzjastycznie Rżnących). The main character of the band is Mirosław Jędras himself, who is the author of lyrics and music, who sings in the band, plays on keyboard instruments and many other (including guitar, violin, pipe). The remaining composition of the group was subject to frequent changes. Currently playing with Zacier are: DJ Mrufka (son of Jędras) on drums, Dr. Yry on bass, Dziarski (Andrzej Matuszczak) on guitar. Since 2013, when Dr. Yry cannot attend concerts due to other duties, the group is supported by Szymen Janowski. One of the first songs of Zacier was the song Odpad atomowy, later performed by Kazik Na Żywo (released on the album Na żywo, but in the studio 1994) and Elektryczne Gitary.
