Win, Will, Régine, and Marika stuck around in Austin for a post-SXSW lecture at the University of Texas on Monday night. According to RollingStone.com, the Arcade Fire members used the appearance to discuss Haiti’s current socio-economic crisis and to urge students to get involved with relief efforts. They also performed acoustic versions of two songs, “Haiti” and “Wake Up”, as ArcadeFireTube points out. Watch footage of the performance below.
