The Act: Macklemore and Ryan Lewis
When and Where They'll Perform: Tuesday, March 12 from 9:40-10:10 p.m. at The Main
Why You Need To Check Them Out: Thanks to "Thrift Shop," these guys are on Cloud 9 right now. They're perched atop the Billboard charts and are no doubt excited about how far they've come in the last few months. But, it'll be interesting to see what kind of reception they get at SXSW and, more importantly, which songs they choose to perform during their set.
