O.N.A. was a Polish rock band formed in 1994 by musicians who had previously played together in other bands. The group included Grzegorz Skawiński as the leader and composer, and Agnieszka Chylińska as the lyric writer and vocalist. Their debut album, Modlishka, was released in May 1995 under MJM Music PL. In September 1996, they signed with Columbia Records Poland and released Bzzzzz, which achieved significant success, earning a 2× Platinum certification in Poland. Their subsequent albums included T.R.I.P. (1998), Pieprz (1999), and Mrok (2001). The band's music was featured in several films, notably the songs "Białe ściany" and "Kiedy powiem sobie dość" in the 2000 movie Musisz żyć. O.N.A. disbanded in 2003, with their compilation album, To naprawdę już koniec 1995–2003, released that same year.
