Genaside II was an influential British breakbeat/rave/UK hardcore band, active from 1989 until 2002, and often cited as one of the pioneers and forerunners of jungle and big beat genres. With Kris Ogden (also known as Kao Bonez and Uzi Da Fluzi) as the founder and principal member, the Genaside II crew originated from South London's Brixton district. Ogden worked with Paul Hamilton (Chilly Phats) on most of the band's core album material, with a rotating cast of members and collaborators over the years.

In 1990, Kris Ogden produced and released the first few 12 singles under the Genaside II moniker on the critically-acclaimed underground label [l1595]. It wasn't until Kris joined forces with Danny Griffiths (of the Archive band), however, that Genaside II gained prominence. Ogden and Danny Gee formed a production duo G Double E, debuting with the cut'n'paste raggamuffin/jungle [m=12848] 12, a Pirate Radio Classic. The next year, they produced and released the massive underground hit [m=17836] for the [l6910] label. With soulful vocals by Sharon Williams and intense breakbeat ragga beats, intesified by the mad vocal assault of Killerman Archer, it became one of the season's bangers on the local hardcore scene. Along with 4 hero's [m=181944], Narra Mine subsequently has been recognized as one of the milestones in early D'n'B history, marking the beginnings of a trend towards a much darker, harder sound.

Genaside II caught the attention of Liam Howlett from The Prodigy, who praised the band's innovative big beat sound. Howlett commissioned the Jericho Remix from Genaside II for the 1992 single [m=12035]. Four years later, The Prodigy reused Narra Mine's core rhythmic pattern in the '96 massive hit [m=12056]. Despite the massive and instantaneous success, Genaside II couldn't capitalize on the established publicity and went on a hiatus for several years due to personal conflicts within the crew, without any new material released for the next four years. By 1995, Kris Ogden revived Genaside II, now producing new music with Chilly Phats. The band got signed by a major dance electronica label Internal, a sub-division of FFRR.

1996 saw the release of their debut full-length album, [m=17846]. The record featured several prominent guest musicians, including Wu-member Cappadonna, who Genaside II met through members of The New Power Generation after they performed together in the United States, Jamaican reggae star Eek-A-Mouse, and vocalist Rose Windross of Soul II Soul. Three tracks were recorded at Wu-Tang Studios, Shaolin in NYC. The project's sophomore album, the '99 [m=17874], came out three years later on Tricky's label Durban Poison. In June 2002, their third and final album, Return Of The Redline Evangelist, followed. In 2021 Kris Bones reactivated GII for a GoFundMe campaign, to support Cameron Dante from Bizzare Inc. He wrote 6 tracks for the project, as part of a compilation that featured numerous artists. It was released via a Limited Edition USB Card titled VISION. There were plans to release the tracks as a standalone EP, but it didn't happen.
