South by Southwest Music officially begins today, but that doesn't mean there was a shortage of shows in the days prior to the festival.  In fact, there was an abundance of parties in Austin over the weekend, celebrating the film and interactive portions of SXSW.  Check out these local Austin bands - Trey Brown, Focus Group (w/ the horns section from Black Joe Lewis & The Honeybears) and The White White Lights - who performed at the ATX Emerege party at The Mohawk on Monday 3/15, and also catch them during the fest.  Remember, there are loads of talented musicians - official SXSW showcasing bands and otherwise - playing tons of free parties in our fair city this week, so be sure to take advantage!
