OR, dubstep's predecessor - Drum and Bass. I like DnB because it kind of feels like an electronic form of metal. Also, if one really wants to feel some low end, look for some of DJ Hype's mixed CDs.
Some of my favorite artists include: Blame, Chase & Status, Concord Dawn, The Jakes Project, DJ Vapour, TC, Mitsubishi, MRSA, Matrix and Futurebound, Noisia, Netsky, J Majik & Wickaman, Sub Focus, Sub Zero, Pendulum, High Contrast, and many, many, more.
