The sound sources used for the pieces range from field recordings to meticulously designed samples. This sonic material is arranged using a number of algorithmic approaches that are always traditionally informed/filtered by the musical choices of the composer. 

 

The six pieces almost feel like miniatures and each has its very own atmosphere and sound world. Despite this there is a strange kind of coherence about the album as a whole. The two percussion-heavy pieces provide it with an inner scaffolding, so that there's a convincing artistic balance to the overall structure that embeds the more onomatopoetic compositions. 

 

Taken as a whole, Tobias Reber's Backup Aura is a fascinating investigation into the organic interplay of human instinct and technology.
