"Arcade Fire have joked about the meaning behind the set of giant beach balls they released during their headline set at Coachella back in April. During their performance at the California-based festival, the Canadian eight-piece - who are performing at London&amp;#039;s Hyde Park tonight - unleashed several hundred beach balls with in-built disco lights into the crowd. When asked by Q magazine about the giant beach balls, lead vocalist Win Butler remarked: &amp;quot;The balls have a life of their own. They have a little mic in them. And also we use them to videotape people in their houses for consumer information.&amp;quot; Butler continued to jest: &amp;quot;And there&amp;#039;s a chip in there so we know exactly where the balls are at all times. It&amp;#039;s actually really powerful because when you combine technology with knowing where people are and the video, then you can know everything about their spending and buying habits, and then you can make music to cater to those wants and desires. &amp;quot;And then you have a hit on your hands.&amp;quot; Following the performance at Coachella, fans lucky enough to grab one of the beach balls managed to sell the props on eBay for up to $1,000. The alternative rock group are due to play a selection of hits from their three studio albums to an estimated crowd of 60,000 people in London&amp;#039;s Hyde Park this evening, including renditions of tracks from their critically-acclaimed LP The Suburbs, which was released in 2010. &amp;gt; Arcade Fire tease &amp;quot;great&amp;quot; London Hyde Park gig Watch Arcade Fire and their beach balls at Coachella 2011 below:      "^^<http://www.w3.org/2001/XMLSchema#string>
