'Spheres' was originally released in 1994. It could be considered the first release of the "middle era" Delerium, seeing Leeb and Fulber starting to move away from the dark sounds of the earlier work into a an approach to ambient that's more spacey and minimalistic. Some of the more ambient pieces here could be easily played along with works such as Brian Eno's 'Apollo' or early Tangerine Dream.
