(from his website)
The project began in 2001 and has continued to blossom to this day. The majority of releases revolve around the ambient and new age genres, but has also delved into neo-classical, dark ambient, and electronica. In 2018, a decision was made for any future ambient-style works to be released through a new project, Loneward. From that point onward, music released under the Altus moniker will used to explore new ideas outside the ambient/new age genre.
