Atheist's Unquestionable Presence is not only one of the most intriguing death metal albums ever made its also one of the best. Boasting Atheist's own self proclaimed genre "Death-Jazz", UP is simply amazing. No album since its release in 1991 has been so ambitious in its concept and so successful in its implimentation. UP is airtight in its construction, with not one waisted note in the entire album, but its greatest acheivement is through the entire album no song seems even the least bit repetitive. Each song on the album posseses its own unique qualities, but still restrains to Atheists core style. The sound created by this album will continue to stun metalheads today, with its complex arrangements/time signatures, precise riffing and solos, those willing to give it a listen will not be dissapointed. There are no words that can describe Unquestionable Presence only a close listen and an open mind can truely understand this albums greatness.
