Not Applicable (Courtnee Fallon Papastathis/Rex) first emerged on mp3.com in 1999, with its first track Infinite Reality immediately topping the ambient electronic charts. Over the next few years through mp3.com, two albums were released; Point of Origin in 2000, and Altercations in 2001. 　　 　　In 2001 Courtnee produced vocals for The Dream Traveler (Joey Fehrenbach) for the tracks Structure and Headpusher. Described as “impressive and emotive”, both tracks were released together as a well-received single through Fade records in 2003. Headpusher was featured on Nick Warren’s Global Underground release Reykjavik. 　　 　　In 2002, Courtnee sang on Scribe Machine‘s album Replicant for the stand-out track Fragile, a top 10 hit on many college radio stations, which was later released as a Maxi-single through Plan B and Tower Records. Somewhere around the same time, she teamed up with Aaron Marshall to create Cirque Des Vampires, and later worked with him again on the song Last Breath. 　　 　　The music of Not Applicable has also been in films, from the college assignment variety and personal projects to the likes of “Horrorvision” (2001) and “Jigsaw” (2002). Holy IMDB, Batman! 　　 　　In 2007, Courtnee self released a compilation of both new and old songs, entitled “Songs of Leaving”. The last of the 50-album limited edition run was sold in September of 2011.
