Italian hardcore punk band from Ferrara, formed in 1980 by Janz, Bistek, Gigo and Aiace.

Infa replaced Aiace on vocals in 1982. A year later, Impact released their first record, the historic, self-produced split 7" EP with Eu's Arse. With another line-up change in 1985–Diego joining on bass and Bistek moving to vocals–Impact released their first LP Solo Odio on Chaos Produzioni (the label of Wretched). They disbanded in 1986, after releasing the Attraverso L'Involucro EP.

During 1989-1992 Janz and Gigo reformed Impact and released Tutto Tace LP and the 7"EP "Inganno Senza Fine." In 1994 Janz was back again with a new line-up and released a split 7" with D.U.S.K.

Impact reformed once again in 2006:
Diego Fabbri - Bass/Vocals
Stefano "Janz" Ragazzi - Guitars
Alberto "Gigo" Gigante - Drums
