A cacophony of electronic bleeps and disjointed drum rolls kick off the second and latest CD "Sensation" by Ryo Kato, aka DJ Klock. What follows is a series of drill-like drum riffs that start, stop then start again several times before settling into a jerky hip-hop-like beat. Later, this transient groove morphs into a swirling drum 'n' bass pattern, before resuming its initial form.

The song, titled "Think Twice About This World," is in many ways the perfect example of how the elements of surprise and juxtaposed ideas characterize much of the 30-year-old DJ and producer's work. For Kato, who made his debut on the burgeoning Tokyo club scene in 2000, music is often a medium he uses to challenge conventional notions of life.

"I think the people are ready to see the world from a fresher perspective," says Kato before a recent club gig in Shibuya. "We live in a society where corporations, the media and government do most of the thinking for us -- as a result, our childlike sensations are being depleted."
