Blue Stone is an American electropop musical project formed by producer/programmer Robert Smith and producer/multi-instrumentalist Bill Walters, and featuring various female guest vocalists.
Robert Smith and Bill Walters are the group's core members, who write the majority and produce all of Blue Stone's output.
Breathe features one guest vocalist, Darcy, on numerous songs, which are a combination of free-form composition and traditional verse/chorus songwriting.
[3][4] Worlds Apart was released in 2007 to uniformly positive reviews,[5] and included three guest vocalists (Rivers, Sandlin, and Hurley), each performing on multiple songs.
This album represented a shift toward a majority of conventionally written (verse/chorus-type) songs that continued in the 2009 release Messages, which was also well received by critics.
