A trailer for "Machete Kills", in which Gaga played La Chameleón, was released on October 4 and previewed an alternative studio version of "Aura". The song's lyric video, directed by Robert Rodriguez, was uploaded onto Gaga's Vevo account five days later, featuring scenes and dialogue from the film. Excerpts of "G.U.Y.", "Artpop", and "Mary Jane Holland" were released periodically over the course of two weeks from October 14 to 28. On October 24, promotional listening sessions of "Artpop" were organized in Berlin, with Gaga providing a live rendition of "Gypsy". She then made an unannounced appearance at London's G-A-Y nightclub two days later and performed "Venus", generating controversy when stripped naked during the show. On October 27, Gaga also played "Venus" alongside "Do What U Want" on the tenth series of "The X Factor" in the United Kingdom. The performance prompted a barrage of complaints to ITV and industry regulator Ofcom, although dismissed by the company. Gaga returned to the United States the following week for a performance of "Dope" at the inaugural YouTube Music Awards, and continued to play material from "Artpop" on "The Howard Stern Show","Saturday Night Live", and at the American Music Awards.
