A video clip is making the rounds on YouTube, featuring English actor Steve Coogan from the United Kingdom television show "Saxondale" talking about the state of disc jockeys in the post-vinyl era.

"What on God's green Earth is that?" Coogan asks incredulously of a club track playing on the car stereo. "These days (to be a DJ) you need to know how to operate Windows XP ... What do they practice? Moving the mouse around?"

Well, maybe.

At this year's Coachella Valley Music and Arts Festival, there were plenty of cursors moving across screens (though to be fair, few of those computers were running Windows XP — more like a variant of Macintosh's OS X). But the new school of DJs playing the festival certainly didn't need practice selecting the right MP3s to play — DJs have embraced MP3s as the format of choice, heading to Web sites like www.beatport.com to download new material and leaving at home the bulky albums and CDs in favor of managing their files with software like Serato Scratch Live and Traktor.

"When you are a vinyl DJ, you have to wait to get tracks on vinyl before you can play them out," says Steve Aoki of Los Angeles, who recently appeared at Honolulu club NextDoor. "Since Serato, you can play anything you produce the second (it's) ready to go — and you don't have to carry crates of records anywhere."

Of course, relying heavily on technology isn't without risk. There's always the possibility of a crash that could bring the party to an abrupt halt.

"I've been pretty fortunate in that I've never had a crash," says electronic artist Deadmau5 (whose adopted moniker is pronounced "Deadmouse" but whose real name is Joel Zimmerman). "I'm using custombuilt software, which helps."

Not every dance music purveyor has been so lucky. British DJ Sasha has been very public about his reluctance to switch over to crash-prone computers when playing live and his subsequent late transition to using a Macintosh G5 instead of vinyl or CDs.

So, naturally, he was the one to experience every DJ's worst nightmare before a high-profile engagement in Miami three months ago during the annual dance music confab known as the Winter Music Conference.

"Ten minutes before I was supposed to play at (South Beach club) Mansion ... I was just about to go on and play and my system crashed," he says. "I made a last-minute call to a friend, and he brought me a spare controller ... I went on a half-hour late and it messed up my entire night, to be honest. If you don't know what caused the glitch, it stresses you out."

Now, though, he's become a convert. Sasha, who played Coachella on April 26, is using Ableton software for his Mac to play live. He says it's a "rare occurrence" that he has a fatal tech error that stops his set and that the "pluses outweigh the minuses" when it comes to using a computer-based platform.

"For the first six months, I was like a kid with a new toy," he says of his relatively new set-up. "But it didn't sound like me ... it's almost like I had to train myself to sound like myself again."

He sighs, adding: "I had to remember that it wasn't necessary to over-layer every track with effects."

Zimmerman, who programs his own sets instead of traditional "DJing," likes to experiment with his own material on the fly, an example being his beloved progressive house track "Faxing Berlin," using code he wrote himself.
