The Dying Process is a song from Lithuria's 2010 release "Pimps of the Living Dead", and to be honest it's some of the best slam death I've ever heard. Easily my favourite album of the year. The tracks are short and punchy, heaps of variance in vocal style, and even some thrash influence. What's not to love?
In terms of metal, Ironman's suit contains a significantly smaller percentage of metal than Lithuria does; as can be seen in the diagram below.
