Whoa whoa whoa Noisia and Pendulum are totally different. First off, Pendulum is a “band”, whereas Noisia is 3 producers, and it shows in the music. Pendulum uses lots of cymbals as a bit of background noise and it shows in their music, and Noisia is a lot darker and bassier. Recently, Pendulum has gone a lot more emo/rock as well and Noisia has gone more dubstep/house, so even though both used to be purely drum and bass they aren’t really anymore.
Also, Split the Atom (Noisia’s album) is better than any of Pendulums.
