I recorded a few women (one of which is my wife) from my church singing Down In The River To Pray a cappella.
Using NanoStudio I remixed it and added to the song, making into something rhythmic and ambient. I only used sounds and tools from within NanoStudio on my iPhone. Invoking some limits usually generates interesting results and forces you to be creative. The results can be surprisingly good. Not saying this is amazing or anything, you’ll have to decide for yourself.
Hope you enjoy.
