"You want bowel-churning mega-bass that shakes the room, demolishes the ceiling, and freaks out the cat?" ask the compilers of this grade-A U.K. techno disc.

Sonic slabs from Orbital, the Chemical Brothers, Underworld, Prodigy, Leftfield and the Future Sound of London, among others, add up to a definitive appetizer tray of drum & bass flavors. --Jeff Bateman
