Spirit Crusher is amazing. Richard Christy's drumming not only on that song, but on the album is IMO really some of the best drumming to ever be recorded in any genre. I honestly think he had the best work with Death. I love Hoglan and Reinert's work with Death, but I gotta say Christy had the most creative drumming out of the three of them.
Had to give this thread a bump since I've been on a massive progressive death metal binge recently (Death, Cynic, Opeth). Also since I jammed with a friend to Symbolic and gave it a raw recording. Control Denied is pretty good Riff, think you should check it out if you havent already.
