Do they write their own music and lyrics? I am relatively new to them,I only have two of their albums. The lyrics and music have different names credited towards them than the band members. I'm not sure of all of their last names though.

Just for example

Epitaph (for humanity)
Lyrics: Lukasz Szurminski

 

[Stinkfist]

I can't find their surname's anywhere, but i'm pretty sure they do write their own stuff.
