The group's new CD/DVD compilation of new and older tracks, "Polysics or Die!!!! Vista" (out on the new MySpace Records label), is ear candy for a generation raised on DJ mash-ups, Ladytron downloads, Japanese anime, and text messaging. As if to affirm the group's of-the-moment niche, Polysics has signed on for the first 30-date MySpace

Music Tour, sharing the bill with other MySpace-bred band phenoms such as coheadliners Hellogoodbye and Say Anything. The tour hits Lupo's Heartbreak Hotel in Providence tomorrow for an all-ages show. So far, the tour - Polysics's most extensive in the United States so far - has been an eye-opener. "The difference that I notice between audiences in Japan and America is that in Japan, people like to blend in, and they will shy away from dancing to live music if the people around them are not dancing," says Hayashi. "Whereas with the US audience, they don't care what other people are doing. Even if there's no one around you dancing, if you like the music, you just dance like crazy. We've been playing in front of a lot of audiences who have never been exposed to our music, and at first they're shocked because the music is new. But as the show goes on, they understand us and get fired up." MySpace cofounder and president Tom Anderson had a similar reaction when he first came across the band on - where else? - MySpace. He later caught shows in Japan and Los Angeles and was immediately impressed. "People go nuts for this band," says Anderson via e-mail. "I've literally never seen a crowd react to a band the way they react to the Polysics. Signing them to MySpace Records was an obvious choice. I wanted to be the person to bring this seasoned band to a new culture and audience. I'm really proud of them."

Part of the audiences' ability to understand Polysics (named after the "Polysix" model of Hayashi's first Korg synthesizer), Hayashi explains, has more to do with feeling its music than it does with understanding the band's hybrid mix of Japanese, English, and what he calls the foursome's made-up "space" language. The band's robotic, synth-heavy version of the Knack's "My Sharona" - an analog to Devo's archly mechanical take on the Stones's "(I Can't Get No) Satisfaction" - is a recognizable touchstone. But other selections, with titles such as "Coelakanth Is Android," "Shizuka Is a Machine Doctor," or "Kaja Kaja Goo," are meant as little more than communicative shorthand: action and reaction, something to shout out to an audience and hear yelled back in unison. Instant communication, instant community.

"When I was listening to my favorite rock music, the lyrics really didn't matter to me," Hayashi says. "What mattered to me was the vocal style or the mood that a song had. So when I started making my music, I wanted my audience to feel the same thing. I had no intention of conveying any message through my music. So this 'space language' came out of that impulse. 'Kaja Kaja Goo' doesn't have any meaning at all. It was just falling down from heaven. The meaning of the word isn't important, but the power that the sound of the word has is important."
