Hanna Leinonen and Tuomas Tuominen appear as guest vocalists on Absence and Anatomy of Life.
The band spent the next October and November making their second album, Absence, which was released April 13, 2005.
The album received praise from Metal Maniacs for being, "...another confident step in turning Noumena into Finland’s biggest new export.” Earlier the same year they released the EP "Triumph and Loss" which was only made available online.
Currently they have created their own label (Haunted Zoo Production) under which they have launched their last three albums, Death Walks With Me, Myrrys and Anima.
The band has stated on their official page that they try to keep their music "Fresh, Experimental, and Versatile" (sic)."
