Blood Sugar was released by Australian drum and bass group Pendulum in 2007, first as a single and later added to reissues of their debut album Hold Your Colour. The track became one of the group's signature songs thanks to its memorable voiceover intro and relentless tempo. It spread through rave culture, gaming videos and early YouTube edits, where creators reused the build and drop structure for high energy moments. It remains a go-to reference for 2000s drum and bass.
