"Diaries & Documents: 2006-2010" is split into two collections of early recordings.
The first tape, "Diaries", is made up of Rachel's earliest sound experiments as she began introducing electronic elements into her music, eventually taking on the Motion Sickness of Time Travel moniker. The pieces range from under 2 minutes to nearly 20 and date from 2006 to 2009. Sound sources include drums, field recordings, guitars, pianos, synthesizers, and voice.
The second tape, "Documents", are all live performance recordings ranging from 2008 to 2010. Side A includes three highly composed performances using either Pure Data or Max patches to generate, effect and sequence sounds. Side B features 4 improvised concerts using combinations of computer patches, synthesizers and vocals.
