Those first two releases served as an inspiration to many of the upcoming black and death metal bands. I do think Sodom reached their musical peak in 1987, but by the time they had fully transitioned to thrash metal it was already a very popular style.
I don't disagree with you. In the Sign of Evil is probably the most influential thing that Sodom ever put out, but what I mean is that Expurse of Sodomy was the debut of Sodom as we know the band today. Those first two releases may have helped spawn a host of black and death metal bands, but without their shift in sound I don't think Sodom would have become as popular as they have.
