KAT & Roman Kostrzewski

Kat & Roman Kostrzewski was a Polish thrash metal band formed by Roman Kostrzewski and Ireneusz Loth after they had left their original band KAT in 2004. Some of the fanbase of KAT views Kat & Roman Kostrzewski as its successor, mainly due to the characteristic vocals of Roman, his lyrics and choice to sing in Polish as in most of KAT's original albums.
