Is the next South By Southwest Music Festival really only four months away? Damn. Time sure does fly, eh? Anyway, the folks behind the event, which features live music from March 13-18, have released the third round of acts added to the ridiculously (and always) huge lineup. This will be the last round we'll be seeing until sometime in early 2012, so be sure to start taking notes about who you want to see and all that. You can view the whole lineup at SXSW's website, but here are some highlights: Talib Kweli, the Big Pink, Built to Spill, A.Dd+, Jonti, Junius, Spoek Mathambo, Soul Khan, and Nguzunguzu.
