The Chemical Brothers - Galvanize (2004)

From Wikipedia: "Galvanize" is a song by British electronic music duo the Chemical Brothers featuring vocals by American rapper Q-Tip. It was released on 22 November 2004 as the first single from their fifth studio album, Push the Button (2005).

The song peaked at No. 3 on the UK Singles Chart on 23 January 2005. It was the Chemical Brothers' highest-charting single in their native United Kingdom since "Hey Boy Hey Girl", which had also reached No. 3 in 1999, and was their last top ten entry until "Go" made number eight in 2026.

Apparently the dance battle featured in the video was called Krump freestyle. Were the kids some kind of Juggalos?
