KNOW YOUR DANCE MUSIC

When it comes to electronic dance music, some of us can't even tell the difference between techno and trance. DJs at tonight's "Do It To It" event will spin genres far more obscure, so we had Mike Davis and Wes Winship tell us about four notable styles you might hear.

The sound: Up-tempo hip-hop beats mixed with house rhythms and repeated vocal samples from TV shows and other pop-culture references.

Key artists: Rod Lee, Blaqstarr, Tittsworth.

At the show: Dave Nada, Plain Ole Bill & Jimmy 2 Times.

Davis says: "To me, it's some of the funnest stuff to play right now. If you play the right song at the right time, people will lose their [expletive]."

ELECTRO The sound: Big synthesized bass lines, distorted glitch patterns. Everything from drums to vocals can be digitally rendered.

Key artists: Daft Punk, Justice, MSTRKRFT.

Winship says: "The bass lines just envelop you. It's easy to just lose yourself."

GHETTO TECH The sound: Early electronic music and '80s funk sped up and mixed with synthetic drums and sexually explicit phrases. Typically faster than most dance-music genres.

Key artists: DJ Assault, DJ Godfather.

At the show: Bitch Ass Darius.

Davis says: "It's like Earth Wind & Fire downing Red Bulls, singing through Speak & Spells, and rhythmically requesting girls to shake their butts."

Key artists: LCD Soundsystem, Rapture, Simian.

At the show: Soviet Panda and the Moon Goons.

Davis says: "People wanted to hear '70s throwback and retro bands, but they want it to be danceable."
