CGA was Andrea’s first published music project who had a focus on musical carpets. Lengthy pieces using sounds as the main driver and mean of composition, as opposed to a more orthodox approach, to evoke feelings, draw atmospheres, and for storytelling. CGA used to publish exclusively on Jamendo under Creative Commons.

In 2012, Aner Andros succeeded CGA. On one hand, with a passage marked by a concentration on internal variety and abstractions, moving from obscure lengthy pieces to denser sound-design-focused music. On the other hand, the approach (composing with sound design) and the goals (atmospheric storytelling) remained true to this day.
