Thou Shalt Suffer were a band that was part of the early Norwegian black metal scene.

Thou Shalt Suffer began in 1990 when vocalist Ihsahn met guitarist Samoth at a clinic for rock musicians.

It was during this time Ihsahn began to develop his skills as a keyboard player, and his trademark sound can be heard on the band's recordings.

Both recordings exhibited a distinct style which would eventually develop into the classic "Emperor sound" of Ihsahn's and Samoth's later careers.

For the time being, Thou Shalt Suffer seems to be on hold once again, as Ihsahn is focusing primarily on his solo career because his previous project, Peccatum, has been terminated.
