Nothing. A friend and I are revamping our old school DM project Satans Henchmen(we recorded a 4 track demo with 5 songs in 2007). I played guitar and he played drums and than he started focusing more on playing guitar forming a doom metal project with 1,2 other people and than recently told me he was writing old school DM riffs so have been working on my own riffs and am probably going over later with my Gear. We're going to set up our shit in his parents big ass garage where drums and bass are already set up with an 8 track and basically handle all the instruments and vocals.
We're basically influenced purely by old school DM like morbid angel,celtic frost,posseseed,death,entombed,dismember,sorcery, all the old school Swedish DM acts etc.. and thrash bands like Slayer,Metallica,Destruction,Sodom,Kreator, and Sabbat.
I think if we record ot will turn out pretty cool.
