We Are Smug is the side project of former Savage Garden frontman turned electropop showman Darren Hayes and collaborator and fellow electronic musician Robert Conley. Hayes and Conley had been working on this project secretly for about two years before releasing it online for free on Hayes's birthday. There are no current plans to tour or sell this album, aside from the free download, but there are already official music videos. (Warning: last link potentially triggering.)
