Ronnie James Dio(主唱)Vinny Appice,(鼓手)Jimmy Bain(节奏吉它)Simon Wright (贝司/键盘)vivian campbell(主音吉它)在1979年 Ozzy Osbourne被开除出Black Sabbath乐队以后曾经做过几年Sabbath的主唱。时间是1979-1982年. 1982年以后, Dio组织了以自己的名字命名的重金属乐队。他招募了一些自己曾经合作过的乐手，作为这个新乐队的成员。 Dio乐队的音乐，歌词主要还是围绕着神秘主义的内容：龙与地下城，魔法师，神话题材等等， 音乐上的处理则很接近Black Sabbath， Ritchie Blackmoore's Rainbow 等等老一代重金属乐队。乐队在1983年发行第一张专辑“Holy Diver”， 取得成功。后来的专辑也很精彩。 进入90年代， Ronnie James Dio参加了重组的 Black Sabbath, Dio乐队基本停止了活动，进入21世纪，Dio乐队发表了一些新作品，但是这几年基本没有消息。For a brief spell during the mid-'80s, the heavy metal quintet Dio was one of the top U.S. concert attractions, boasting one of the most over-the-top stage acts of its time loaded with props and special effects (lasers, explosions, a giant dragon, etc.). The group's leader was singer Ronnie James Dio, who had previously become acquainted with the metal masses as the frontman of Ritchie Blackmore's Rainbow from 1975-1978 and Black Sabbath from 1979-1982. Come the early '80s, Ronnie James was ready to finally head out on his own, forming Dio and recruiting a stellar backing band, consisting of a few former bandmembers, ex-Rainbow bassist Jimmy Bain and ex-Black Sabbath drummer Vinny Appice (Carmine Appice's brother), in addition to ex-Sweet Savage guitar shredder Vivian Campbell. Lyrically, the group would retain the same subject matter that Ronnie James specialized in with his previous outfits (dungeons and dragons, swords and sorcery, damsels in distress, etc.), but musically, Dio was more melodically based than Rainbow or Sabbath. The group scored a hit right off the bat with their 1983 debut release, Holy Diver, which spawned such popular MTV videos as "Rainbow in the Dark," as well as its title track. For their sophomore effort, 1984's The Last in Line, the band expanded its lineup to include keyboardist Claude Schnell, as the album would become the biggest hit of Dio's career (on the strength of another MTV-approved video, for the album's anthemic title track) and the group became an arena-headliner. Although Dio's next release, 1985's Sacred Heart, was commercially successful, Campbell had become disillusioned by the group's direction and split from the group a year later. Just prior to Campbell's exit, the entire Dio band helped organize Hear N' Aid, an all-star assembly of heavy metal artists that recorded a track called "Stars," which helped fight world hunger (a subsequent album was issued as well, collecting previously unreleased live tracks from a few of the day's top hard rock acts). Former Giuffria guitarist Craig Goldy took Campbell's place, resulting in such releases as 1986's live EP Intermission and 1987's Dream Evil, which retained the group's headbanging audience, but failed to expand upon it as its previous releases had. By 1990's Lock up the Wolves, Ronnie James Dio was the only original member of Dio left in attendance as the band's lineup continued to fluctuate throughout the '90s on such releases as 1994's Strange Highways, 1996's Angry Machines, and 1998's Inferno: Last in Live (Ronnie James took a brief break from Dio in 1992 to rejoin Black Sabbath for a lone release, Dehumanizer). In 2000, a pair of Dio releases emerged; first was Dio's first new studio album in four years, the concept album Magica (which saw past members Bain and Goldy return to the group), as well as a 16-track compilation titled The Very Beast of Dio. His medieval-themed metal returned two years later, when the Killing the Dragon album arrived in the spring of 2002. The album was a serious endevor, but Dio also learned to make fun of his image after years of defending it, inviting comedy duo Tenacious D to star in the video for "Push" and even including the clip on the fall re-release of Killing the Dragon.
