With fast, aggressive music and lyrics filled with obscenities, the band was a sensation at the 1984 Jarocin Festival.

In October 1984, after a performance with TZN Xenna and Youth Brigade, Budzynski left the band following a dispute with Adamski over control in lyric writing.

Tomasz Adamski reformed Siekiera with two new members: Zbigniew Musinski - drums and Pawel Mlynarczyk - keyboards.

In 1985 they played again at the Jarocin festival, but the orthodox punk public did not like their new wave image and music.

In 1986 Siekiera released their only LP, Nowa Aleksandria - it is influenced mainly by Killing Joke and regarded as one of the greatest Polish albums of all time.

They were expected to re-form in 1989 with an almost original line up (with Stopa who used to play in Moskwa and Armia as the drummer), but somehow it did not work out.

In 2014, the Polish black metal band Behemoth, covered Siekiera's track "Ludzie Wschodu", on the Australian version of their album The Satanist.
