POLYSICS是一支在日本活跃了很久的男女组合，以电音摇滚为主，曲风欢快活泼有时还有些疯狂。
POLYSICS成立于1997年，基于团长HAYASHI对DEVO(1975年组成，new wave乐风的先驱)的喜爱，所以组成了这个团。第二年加入了SYNTHESIZER手KAYO。根据GIGS杂志提到，KAYO其实是个古典底的钢琴手，但是很可惜的，在POLYSICS绝对听不到跟古典乐有任何的关係。可以听到的是new wave到极点的合成器以及音效。(日本keyboard杂志在访问他们时提到的是MOOG以及CLAVIA两个经典牌子的new wave SYNTH)虽然他们只有两个人。但还是在1999年在UK project这个独立厂发了第一张专辑：FIRST P。
一直到现在他们玩的还是一样，疯狂的摇滚乐加上NEW WAVE的电子键盘音效。你可以听到很PUNK的歌曲，也可以听到怀旧80新浪潮，也可以听到融和两种乐风的新变种POLYROCK。他们在日本已经在Ki/oon发行了4张专辑Neu、ENO、For electric young pop、National P。2004年发行美国巡回live DVD，第二次再去美国巡回14个城市。年尾发行精选辑Polysics OR die。收入了6张专辑内的歌。之后随即展开全日本巡迴表演。也在ki/oon的tribute to Newwave的专辑中，翻唱了softcell的歌曲memorabilia。2005年加入新鼓手，而今年他们也刚从英国以及西班牙巡迴回到日本。
在日本他们曾经参加过summer sonic、Fuji ROCK、Rock in Japan、日本大型演唱会机乎都可看到他们踪影。而且重要的是他们不是录音室乐团，现场才是他们胜利的决定关键。
POLYSICS的现场充满了戏剧性，他们跳著机器人舞，也像DEVO般穿著奇装异服。KAYO弹KEYBOARD的时后总是一动都不动。这也成了POLYSICS的招牌之一。在其他三个动得乱七八糟的人之中你可以看到有个女生一动也不动的唱著歌。他们是会让你感到真正摇滚魅力的摇滚乐团。
A violently energetic amalgam of fractured punk rock and vintage video game sound effects, Polysics gained recognition quickly due to their spastic live shows and trademark uniforms: matching orange or yellow boiler suits, straight-bar sunglasses, and badges stamped with the letter P. The band was formed in 1997 by Japanese high-school student Hiroyuki Hayashi, who named the group after his first keyboard, a Korg Polysix. After watching some live footage of Devo and becoming heavily inspired by new wave music of the West, the fledgling frontman/guitarist decided to quit his soccer team and form a band that would expand on the cartoonish image and musical ideas of the zany art-punk icons he had seen on TV. He linked up with drummer Junichi Sugai and Sako (aka Poly 2), who took the role of singing vocoded robotic vocals and driving the low-end through a bass synthesizer. The antithesis of spastic performers, Kayo, also joined the band, and her stoic, mechanical stage presence on the synthesizer and vocoder combined with the other members frenetic live antics made for an strangely lopsided but exciting stage dynamic.
While leaving their mark on the blossoming J-rock scene, Polysics were picked up by local indie label Deckrec and U.K. label Project, which released their first record, 1st P. Poly 2 left Polysics soon after, and a more rockin, less synth-oriented record followed that October, titled A.D.S.R.M! While the trio made plans to embark on a national tour, Asianman Records released the groups U.S. debut, Hey! Bob! My Friend!, a compilation of songs from their first two Japanese albums. In April of 2000, just after performing in Austins South by Southwest Festival, Polysics signed to Ki/oon Records (a subsidiary of Sony Music Japan) and released two maxi-singles, XCT and Each Life Each End. That summer, after a series of club dates, the group released the wonderfully frantic Neu in September of 2000. For an extensive tour of Japan, the group enlisted bassist Fumi and the new lineup recorded and released Eno that July. The band began generating a buzz overseas due to the inclusion of Polysics on a series of Japan for Sale compilations that showcased the talents of notable Japanese musicians, and relentless touring and recording ensued before they finished the melodic For Young Electric Pop in April of 2002.
The next year, Sugai departed and was temporarily replaced by Ishimaru (drummer for the punk group Snail Ramp) just before Polysics left for a coast-to-coast tour of the States, where Neu had just been released. In what was proving to be a grand year for the band, Polysics started receiving worldwide recognition during 2003, and after a performance of Kaja Kaja Goo on the BBC2 TV show Adam & Joe Go Tokyo, Kaiser Chiefs frontman Ricky Wilson took notice and invited the members to open up for his band on a future U.K. tour. In 2004, a greatest-hits album, Polysics or Die!!!!, was released on Tofu Records, followed by their most accessible studio album, Now Is the Time!, in 2005. Yano replaced Sugai on the drum stool and Polysics returned to the tour bus for their largest tour, with 96 shows in six countries, in support of the Chiefs.
Fueled by an unstoppable work ethic, the group returned to the studio to record the Japan-only release Karate House on Ki/oon in February of 2007, and put out a series of videos for the singles Electric Surfin Go Go, You-You-You, and Catch on Everywhere. That spring, after Polysics signed a territorial license deal to MySpace Records, the up-and-coming U.S. label started making plans to re-release Polysics or Die!!!! in the States, with the inclusion of the latest singles from Karate House and a bonus DVD of videos and live cuts. The comprehensive Polysics or Die!!!! Vista was released on October 9, 2007, marking their ten-year anniversary.
