Siekiera (Axe) was one of the most influential and popular post-punk bands in Poland. With fast, aggressive music and lyrics filled with obscenities, the band was a sensation at the 1984 Jarocin Festival. After lineup changes, the band switched to new wave and dissolved in 1988. Siekiera formed in 1982 or 1983 in Pulawy, Poland, under the name of "Trafo". The line-up then was Tomasz Adamski - guitar, Tomasz Budzynski - vocals, Jerzy Janaczek - bass, and Borys - drums.
