called "Get Yourself High". Singles 93–03 was also released on DVD, with extra features including selected live performances and interviews with Rowlands, Simons, and many of their collaborators from throughout the period. "Get Yourself High", which featured Canadian rapper k-os on vocals, was released as a single in November 2003. In late 2003 and 2004, the Chemical Brothers continued to work in the studio on new material and a remix of "Slow" by Kylie Minogue. After being released on rare white label vinyl, it was subsequently given a commercial release in March on CD (on her next single "Red Blooded Woman") and on 12-inch vinyl picture disc (containing two other Minogue remixes). In Summer 2004 they returned to the festival circuit, including appearances at the Glastonbury Festival, Tokyo, Scotland, and Ireland. They also visited South America for the second time (the first time being in 1999), arriving at Chile, Argentina, and Brazil. It was during these sets that they played new material, including "Acid Children", which proved to be one of the most popular new tracks. In September 2004, the Chemical Brothers released the seventh "Electronic Battle Weapon". "Electronic Battle Weapon 7" was being released as a one-sided promo-only 12-inch, containing "Acid Children". A marked departure from the Chemical Brothers' previous musical endeavours, it featured a screeching 303 bassline and a distinctive vocal sample; a pitch-altered vocal sample proclaiming "You Are All My Children Now!", which is lifted from the horror film A Nightmare on Elm Street 2: Freddy's Revenge. It was coupled with the projection of a sinister clown mouthing these same words at their live gigs. The "Electronic Battle Weapon" series of promo releases have typically been newly recorded Chemical Brothers tracks, released on promo to allow DJs to test them in a club environment, and to gauge their popularity. In 2004, the Chemical Brothers began work on Push the Button, their fifth studio album, which features collaborations with Tim Burgess, Kele Okereke, and Anwar Superstar, amongst others. The album was released on 24 January 2005. "Galvanize", which features rapper Q-Tip on vocals, was the first single to be taken from Push the Button, and premiered on iTunes. The single was released on 17 January 2005, and entered the UK chart at No. 3. The second single, "Believe" (featuring Kele Okereke from Bloc Party), failed to crack the top 10, but still made it into the top 20,
