You can depend on Solange to be the best dressed anywhere — that pink suit! — but her commanding live presence at SXSW is a thing of wonder, even if her funky R&B can be quiet and unassuming. We also took in the crushing doom metal of Batillus, spazzed out to Metz, and got gloomy with Diamond Rings. And file this under Unexpected Guests: Usher got onstage with The Afghan Whigs during a of cover of "Climax." Really. See a gallery of photos here and follow us on Flickr for much, much more.
