Within the series Self.Defense.Unit, master Rickson Gracie teaches invisible aspects of the self-defense. This is the first time ever that Rickson, arguably the best Jiu-Jitsu fighter of all times, filmed instructional videos. This is only a teaser of the in-depth classes he teaches on his SDU course (the whole course is on http://selfdefenseunit.com).
