Introducing: EXILE TRIBE

EXILE TRIBE is another Japanese mess of brother- and sistergroups, units, collective units and subunits. But they're awesome. Their basic idea is that they have vocalists & performers separated - some members of the group are purely dancers. Here's a chart for you to understand the parts of EXILE TRIBE:

Simply: HIRO created J Soul Brothers, which became EXILE. Later, second (Nindaime) and third (Sandaime) generations of J Soul Brothers existed. THE SECOND from EXILE is basically the same group as Nindaime J Soul Brothers. There's also a unit called Generations (from EXILE TRIBE) and some other minor units. Many of these artists above are also part of the main group EXILE. E-Girls is short for EXILE Girls unit, and it consists of units Dream, Flower and Happiness as well as some original members.
EXILE TRIBE is a collective name for these units.
There was nothing simple about that.

What is simple is that their music is great. And that their "Short Versions"
of songs usually last for 5 minutes. It's heaven.
