Australian band ANUBIS was formed in 2004, and the specific aim of the band was to create a concept album. While the plan initially was to honour a dear, departed friend by writing the album in his honour, they have chosen to make this person a more anonymous inspiration as the work progressed. Anubis describe the final result as pure fiction, while the protagonist became anonymous to represent the fact he wasn't actually anyone at all. The final result of this process was finalized in 2009 as the album "230503", and was made available in digital and physical formats towards the end of autumn the same year.
