Those looking to cook up some crystal meth will have to seek out alternative chemical pastures now that ephedrine has landed on the national no-no list. Fortunately for the rest of us, there's still plenty of Crystal Method to be found. The Las Vegas-via-Los Angeles duo has been brewing its own brand of danceable electronica for more than a decade. On their third full-length, Legion of Boom, Ken Jordan and Scott Kirkland enlist help from an eclectic guest book that includes former Limp Bizkit guitarist Wes Borland, Roots mouthpiece Rahzel, and actress and occasional songstress Milla Jovovich. The result is an epic rave, guaranteed to keep you tweaking into the wee hours.
