Rammstein are bold experimenters, as are others who interpret their music. Surprisingly, Pet Shop Boys remix “Mein Teil”, drowning the German ragers' metal in big-room synths and raver beats, and Meshuggah accentuate “Benzin”, morphing it into a grinding exercise of start-stop guitar riffing. Rammstein's “Laichzeit” is a tight alt-rocker laced with fidgety loops that reveal their debt to electro-industrial.
