During the spring of ´94 IMPIOUS was formed by Valle Adzic and Martin Åkesson, brought together by an ad in the local music store. The band had some difficulties finding a permanent drummer, so a friend called Johan Lindstrand filled in as a session drummer. Shortly after that Robin Sörqvist joined the band to play the bass. IMPIOUS recorded their debut demo in the summer of ´95. The opus is called "Infernal Predomination" and sold about 150 copies.

Shortly after the recording session drummer Johan had to quit the band due to lack of time, since he had to do the military service. Well, no tears shed. The band was looking for a permanent member anyway. But that turned out to be harder than expected. No drummer was found, so another friend called Marko Tervonen filled in, also just as session drummer. So in May ´96 the band recorded their second demo, called "The Suffering". The recording took place at Los Angered Recording, with producer/engineer Andy La Rocque. The demo got some really great response, but no label actually ended up signing the band. Shortly after the recording a permanent drummer was finally found! Ulf Johansson accepted the job and this was the first time the band felt "complete".

In the summer of ´97 IMPIOUS recorded their third demo simply called "Promo ´97". This demo never got to be released. At the same recording session, the band recorded a Sepultura cover for the Black Sun tribute album "Sepulchral Feast". IMPIOUS covered the song "Inner Self". "Promo ´97" resulted in a record deal with Swedish label Black Sun Records, and in december ´97 IMPIOUS recorded their debut album "Evilized" in Sunlight Studios with producer Tomas Skogsberg. The album was released in the summer of ´98. Later that year in october the band entered Los Angered Recording once again, this time to record a Metallica cover for the tribute album "Metal Melitia III". The song "One" was covered

´99 was a quite lame year for IMPIOUS, but in January ´00 the band recorded their second album in Studio Mega with producer Chris Silver. Unfortunately it took almost a year for Black Sun to release the album.

Anyway, in the summer of ´00 IMPIOUS decieded to make some drastic line-up changes. Martin, who had always sang and played the guitar, quit playing the guitar to concentrate on the vocals. Robin switched from playing the bass to handling the lead guitar. And since Robin actually is a better guitar player than both Martin and Valle, this was a smart move. So, there was an empty gap to fill in the band. So a friend called Erik Peterson was asked to join the band to play the bass. He accepted.

According to IMPIOUS´ contract with Black Sun a third record was supposed to be released, but the band was free to leave the label anyway. So, in March ´01 IMPIOUS recorded a four song promo in Studio Mega. The promo was sent to different labels with the intention to get a deal. After looking at offers from some labels, IMPIOUS decided to sign a deal with Hammerheart Records.

In February ´02 drummer Ulf Johansson left the band, just five weeks before the recording of the third album. But IMPIOUS immediately found a substitute. His name is Mikael Norén and is one hell of a drummer. In just a few weeks he learned the band´s all 10 songs for the album. So in March ´02 the band recorded their third album "The Killer", once again in Studio Mega with producer Chris Silver. Today´s line-up is stronger than ever, and IMPIOUS just keeps improving and growing as a band each day that passes by.
