Can machines create original music? 

Scape is the answer to that question.
Scape makes music that thinks for itself. From Brian Eno and Peter Chilvers, creators of Bloom, Scape is a new form of album which offers users deep access to its musical elements. These can be endlessly recombined to behave intelligently: reacting to each other, changing mood together, making new sonic spaces.
It employs some of the sounds, processes and compositional rules that have been used by Brian and Chilvers for many years and it applies them in fresh combinations, to create new music.
