There are at least two groups called Planetary: 1) Planet, or Planetary first appeared in the hiphop duo OuterSpace, together with Crypt (Crypt the Warchild). Here's their Biog. Outerspace is the brainchild of Philadelphia MC's Planetary and Crypt the Warchild. The philosophy of Outerspace runs much deeper than music; it's literally a family. The two founding members have been friends almost since birth and found a common bond in the music they grew up on such as Gangstarr and EPMD.
