Lady Gaga performed at South By Southwest last night, and while the ARTPOP singer's record sales may have been disappointing lately, her flair for viral provocations remains fully intact. During the song "Swine," as FACT points out, the performance artist Millie Brown — known for painting with her own vomit — appeared to drink a green liquid and then puke it up all over the Mother Monster. Now that's something you legitimately don't see at just any concert. This was Texas after all, so Gaga also gave a nod to barbecue by having herself tied to a giant roasting spit while performing fellow ARTPOP track "Aura." Watch the vomiting "Swine" above and the spit-roasting "Aura" below, and check out the dates for this year's "ARTPOP Ball" tour.
