Composed for ICMC 2014, Athens and premiered at the Onassis Center. The music is completely generated from scratch using a software implementation of dynamic stochastic synthesis, an algorithmic  non standard synthesis procedure conceived initially by Iannis Xenakis. It uses mathematical concept of random walks to produce both duration structure and timbral fluctuations in computer generated sound, resulting in a wide gamut of sonic entities. An original version of the algorithm and the whole piece were written in Supercollider language. Stocos proposes an extension of the Xenakian algorithm using swarm simulations to modulate the parameters that define the dynamic stochastic algorithm.
