Kirk wrote a couple of riffs in Exoodus that were never released and that he used in Metallica later on, except for one, trapped under ice, which was used in impaler on the tempo of the damned album in 2004, and he actually wrote a couple of riffs that were used on the bonded by blood album that he didn't use in metallica. the master of puppets riffs were written by james and kirk and one of the riff was a riff kirk wrote back in exodus i think cause it sounds pretty much the same
why wasn't death and domination released on an album, the song is awesome! but i guess the song sounded to much like nwobhm, after all the bay area thrash bands were very much inspired by nwobhm but exodus wanted to have a more extreme sound i guess
