remixes, plus Electronic Battle Weapon 4, named "Freak of the Week", and a track called "Enjoyed", which was essentially a remix of "Out of Control" by the Chemical Brothers themselves. A CD copy of Surrender was placed in the third Blue Peter time capsule, buried in January 2000. That same month, they appeared on Primal Scream's album Xtrmntr at track 11 with a remix. In June 2000, they played the Pyramid stage at the Glastonbury Festival. In August 2000 they played to a large crowd at the main stage at Creamfields festival, Ireland. In December 2000, the Chemical Brothers aired one of their new tracks, "It Began in Afrika" at their New York DJ gigs, supporting U2. In 2001, they were active with releases and live performances. Early in the year, they began working on a fourth album, provisionally titled Chemical Four. The first track which fans got a taste of was "It Began in Afrika", as previously played in their DJ set in New York. The track would make its live debut in California in April 2001, at the Coachella Valley Music and Arts Festival. Another new track, "Galaxy Bounce", also got its public debut at Coachella. As had become customary for their releases and experiments, "It Began in Afrika" was first pressed as a promo, as part of the "Electronic Battle Weapon" series. It received much airplay on dance music radio shows in the UK, and became more and more popular in clubs over the course of the summer. It also became one of the "anthems" in Ibiza as the summer progressed. It was given a full commercial single release in September, reaching No. 8 in the UK singles chart, even though no promotional video was made for the track. Rowlands and Simons also remixed a track from Fatboy Slim's Halfway Between the Gutter and the Stars, entitled "Song for Shelter". This remix was released as a single on 3 September 2001 (one week before "It Began in Afrika") as the CD2 single for "Song for Shelter / Ya Mama". It reached No. 30 in the UK Singles Charts (sales were combined with the CD1 single). The Chemical Brothers finished work on another album, Come with Us, in October 2001. It featured collaborations with Richard Ashcroft of the Verve ("The Test"), and long-time collaborator Beth Orton ("The State We're In"). The album was released in January 2002, preceded
