Ringtone Symphony is a retrospective of unfinished, abandoned, or otherwise unreleased tracks from the last 7 years, found on a cloud long after the hard drives had failed. A kind of protracted time capsule in damaged, neon electronica.
Some tracks have been remade or modified when source files were available, in an attempt to Special Edition a Jabba into a scene here or there. But Han still shoots first. So at least there's that.
