Lady Gaga gave a performance at the 2014 SXSW festival that included "vomit art," which she later explained at a keynote address was all about promoting the freedom of artistic expression. "Things that are really, really strange and feel really wrong can really change the world," she said. "I'm not saying vomit's going to change the world. ... It's truly just what we wanted to create and do." How does the singer's SXSW appearance hold up against her other spectacular looks?
