I am compiling a soundtrack to help me get into the right headspace for writing Indigo. Peter Himmelman's Synesthesia album came first to mind, as did various selections from Talk Talk and David Sylvian. Are there any other artists or songs my f-list can recommend that have the right feel to them? I'm looking for stuff that's atmospheric, complex and slightly dark; experimental yet still melodic; nothing too angry or dissonant, but nothing too fluffy and simplistic, either.
Suggestions, links etc. welcomed in comments.
