If you don't know what SXSW means, it's South By Southwest, and it's a huge movie and music festival that has grown to gargantuan size.  Growing to a guesstimated 25,000 attendees this year alone.  Brand new musicians and film makers use it as a way to network and debut their material, and veterans of the industry stay on top of the game with performances and appearances.  For Hip Hop, the Shady 2.0 showcase was a big night for the festival.  50 Cent headlined, following performances from Action Bronson, ScHoolboy Q and Big K.R.I.T. and foursome Slaughterhouse which includes Crooked I, Joe Budden, Joell Ortiz and Royce da 5'9".

Here is video of the height of the evening, when Eminem himself comes out for a verse on "Patiently Waiting" with 50.
