本名 John Dadzie，但因艺名 12th Planet或Infiltrata而被人们所熟知。这位Dubstep风格的DJ/制作人来自美国洛杉矶。他将Bass和Dubstep音乐带到了北美主流人群的视线中。
Born John Dadzie but known artistically as 12th Planet or Infiltrata, this dubstep DJ and producer hails from Los Angeles, U.S. He is known for bringing bass music and dubstep to the North American mainstream.
Dadzie成长于LA的南部。他第一次发现电子音乐还要追溯到高中时期的一场Raves and Jungle派对。在使用Infiltrata作为艺名期间，Dadzie联手DJ Lith创立了厂牌Imperial。这个全新的厂牌让他能在纯正的Bass和Drum Beats上大展拳脚。
Dadzie grew up in the southern part of Los Angeles. He first discovered electronic music in high school at raves and jungle parties. Under the DJ name Infiltrata, Dadzie joined forces with DJ Lith to create Imperial Recordings. The new label allowed him to produce original bass and drum beats.
2006年，Dadzie跨越到了一个全新的音乐领域：Dubstep。他的新艺名：12th Planet暗指了那本作者为Zecharia Sitchin，名为《The 12th Planet》的小说。在小说中，作者对一个构想出的星球，Nibiru进行了理论具象化。一些极客们评价他的音乐就像“去the 12th Planet旅行然后回来了”一样。
In 2006 Dadzie took his musical career towards a new direction: dubstep. His new musical alias 12th Planet alludes to the novel “The 12th Planet” by author Zecharia Sitchin, which theorizes the existence of another planet called Nibiru. The sci-fi geek explains his music is supposed to feel like “a trip to the 12th planet and back.”
