Uncertainty5 is the 21st release and 18th album-a-day by composer and electronic musician Adhesion. It is also the 5th in the Uncertainty series, indicating that in addition to being an AAD, it is also a deaf ear AAD, in which the music is not listened to at all while being composed and produced. Unlike the previous entry in the Uncertainty series, this one is a return to the electronic stylings of the first three, with a mix of IDM, techno, ambient and noise. Recommended tracks include Bring it Down, an epic IDM song with lots of dynamics, Forced Compliance, dark pseudo-breakcore in strange time signatures, and Stolen Heaven, an experimental ambient track with lots of arpeggios. Written and produced entirely in software on July 21st, 2007.
