SXSW 2013 rages on. We've put together a recap of some of the key events of Wednesday, March 13, which featured sets from Yeah Yeah Yeahs and Paramore, where they debuted new songs, while pop waif Sky Ferreira delivered a questionable perf.

Read on to see what you missed and in some cases, you can experience it via the miracle of video footage!

Paramore: At the Warner Sound Showcase at the Bellmont, Paramore debuted their brand new single 'Still Into You,' even though were are still into 'Now,' the first single from their forthcoming effort 'Paramore,' during their 1AM set. The band also covered a few bars of Fleetwood Mac's 'Landslide' in the middle of their own song, 'In the Mourning.' Plus, we love Hayley Williams and her fiery red hair. [Listen Here]

Chvrches: The Scottish electro pop trio played the Windish Agency showcase. They are also buzzing, having only released the single 'The Mother We Share.' A three-song EP due out this month, with a full length to follow in September. Frontwoman Lauren Mayberry was reportedly shaken by nerves, likely due to the fact that it's SXSW for God's sake. Totally forgivable, though.

Yeah Yeah Yeahs: The alt rock stars performed several new songs from their forthcoming album 'Mosquito,' including 'Sacrilege' and 'Subway,' as well as the title track. The set at Stubb's BBQ was off the chains and exhilarating, with frontlady Karen O showing off blonde hair and a bedazzled, Elvis-like jumpsuit. [Watch Here]

Kitten: Meow! Sources say that Kitten's Chloe Chaidez was all over the stage, climbing atop gear cases and singing. We love a girl with balls.

Sky Ferreira: We heard that darling waif Sky Ferreira had an off night and left the stage in tears. That's too bad, since we love her new sound. Everyone's entitled to bad days or imperfect perfs!

Bastille: The British rockers cranked the amps and the singer has some wild and crazy hair. [Watch Here]

twenty | one | pilots: The Ohio duo opened for Paramore and they erase the lines between genres, mixing pop, indie rock, rap, electronica and more in avant garde fashion. Singer Tyler Joseph is a wild man -- he's been described as "schizophrenic" when he performs. The twosome are like mix of Eminem, the Strokes and Mumford and Sons. Go fig!

Lucy Rose: At the ACC Ballroom, the U.K. singer performed her set with a full band. The buzz about her is that, well, she's a buzzy artist of SXSW. She's adorbs -- love her bangs -- and has such a lovely voice.

Iggy and the Stooges: The punk icons played classics (like 'Raw Power') and sprinkled the new track 'Burn' among others during their performance. Burn, baby, burn!

Earl Sweatshirt: While Tyler, the Creator and Frank Ocean get the most attention from the Odd Future collective, don't forget about Earl Sweatshirt, who was MIA and in another country for a while, with his musical future largely in doubt. He performed new songs flanked by Flying Lotus and Domo Genesis. He sampled new material from 'Doris' and closed with 'Earl.'
