There are at least three artists named Radix:

1. Swedish Scene Music Composer. Free downloads available at: http://www.mosaik.se/
Known pseudonyms: radix sinespree Rymdlego mosaik

2. American hip hop act from Boston, Ma.

3. Punk/Rock/Folk band from around Allentown, PA.

Randomly selected college roommates, Quite Nyce and SEEK found each other creatively while writing a track together for an upcoming Quite Nyce album.
After a fall out with the label that Quite Nyce was signed to, he met with SEEK and other investors to start their own record label. After countless hours and sleepless nights Abstrak Recordings was launched early 2003, which also gave birth to RADIx (Quite Nyce and SEEK).
Six releases and over 300 concerts later RADIx (Quite Nyce and SEEK) are one of the top groups in Boston, Ma. The innovative and complex rhymes they press on wax spill over in the form of their live set. Intricate 'back and forth' rhyme schemes combined with energy and hyped crowd participation equals RADIx live.
