There are multiple artists named Sandcastle:

1) Sandcastle is a solo project founded by Elena Sands as a side project of her first neoclassical darkwave music experiment called Gothic Lethargy that has existed since 1997. The music style of Sandcastle can be defined within several styles from neoclassical and ethereal to gothic and darkwave.
The very idea of Sandcastle appeared in March, 1999, with the new material that sounded more progressive and melodic than old Gothic Lethargy works. This new stuff couldn't be recorded properly in a very small and poorly equipped home studio.
For almost four years Elena Pravikova (aka Elena Andersson), born and raised in a provincial Russian town, had to deal with extremely bad social and technical opportunities for realizing her ideas. In spite of this fact she continued to record the new music from time to time and stored it on tapes that are a bit more reliable than memory. Some of these interesting, but almost destroyed recordings were used on Sandcastle's first instrumental album "Per Aspera ad Astra" that was recorded between 2003 and 2004 in Sweden.
