This CD consists entirely of Composition no. 77, composed by @c (Miguel Carvalhais and Pedro Tudela, Portugal). “77” started to take form in early 2007 and was developed until late 2009. Many of the sounds in this composition were created for the soundtrack of an installation by Lia and Carvalhais, dealing with concepts as liquid motion, flow, turbulence, percolation and phase transitions, which inspired the creation of several sound files sorted in three different groups, one for each section of the installation.
