In 2008 the band released under Unique Leader records their first internationally recognized success The Vile Conception.
This album set the coordinates for their sound, marked by a technical guitar riffing, blast beats and fast vocal lines.
In 2010 their fourth album Paradogma was released, and while keeping the brutal approach of the previous work, their sound incorporated more melodic and black metal influences.
The album was recognized by the press as one of the death metal highlights of the year and opened the road for a deal with the Los Angeles based label Prosthetic Records and a tour with Deicide.
Hour of Penance then signed a deal with Polish label Agonia Records and released a new album called Misotheism on October 25, 2019.
