SleepWalks (2009-ongoing) - an overnight, live electronic music performance exploring the impact of sound on dreams by playing to a sleeping audience who then journal about their experience in the morning. The goal of this long-term project is to compose engaging soundwalks for dreamers; to compose soundwalk experiences in participants' dreams.  Lee Pembleton and Andrea Williams cull sounds from their audio files of field recordings, live samples of the room resonance, and various electronically processed acoustic instruments, to create an extended musical composition for an audience who are encouraged to sleep in the performance space.  Using Ableton Live audio software on their laptops, Pembleton and Williams record the sound samples they use during the performance. Later by reading the timestamp, they make possible correlations between the sounds in the composition and writings from the participants' dream journals.  Sleepwalks has been performed at numerous venues including Issue Project Room, NYC; Diapason Gallery, NYC; and Mills College, Oakland, CA as part of The Deep Listening Institute's Dream Festival.
