WATCH: Austin City Limits Festival 2012 Highlights [Day 2]

This year's Austin City Limits Music Festival proved to be one of the most successful to date. Hosted on the grounds of Zilker Park, the final one-weekend event (2013 will be stretched to two weekends) included a full roster topped by The Red Hot Chili Peppers, Neil Young and Crazy Horse, The Black Keys, Jack White, Florence + The Machine, The Avett Brothers, AVICII, BASSNECTAR and The Roots.

As you know, we covered the entire event from Friday, Oct. 12, through Sunday, Oct. 14., providing live tweets, interviews and photos all day/night. But here are some of the highlights:

SATURDAY (Day Two)

The day opened with sets from Quiet Company and Caveman, smaller bands who are both gaining momentum as of late. Caveman, specifically, had a busy weekend, performing multiple times that day with appearances at the Xbox Lounge for press later that night. Unfortunately, as Civil Twilight took the stage, looming rain became more certain. Prior to the Festival's start, weather was already a topic of discussion (it rained Thursday night as we were arriving in Austin). But Civil Twilight -- natives of South Africa, who were featured earlier this year in Variance -- played on, and gave Austin a wonderful, lively show. Clouds turned to light rain as Dev opened with her hit "Bass Down Low" before a noticeably younger audience. Despite only casually dubbing vocals over her tracks, she probably had one of the most engaged crowds all weekend. Her energy was certainly not lacking, and at times the audience came close to matching her volume as they knew every lyric to her songs, such as "In The Dark" and Far East Movement's "Like A G6," a song on which she was featured.

WATCH: Bad Books' Kevin Devine & Andy Hull Talk New Album, Future

Andy Hull (of Manchester Orchestra) and Kevin Devine made a stop at this year's Austin City Limits Music Festival to perform as their new act Bad Books. We caught up with them before their set to discuss their relationship with each other as musicians and friends, and how they came together to form the group. Devine, who has successfully toured solo prior to Bad Books, also revealed the identity of his No. 1 fan.

FRIDAY (Day One)
First up on our schedule were Colorfeels and First Aid Kit -- the Nashville-based indie group and Swedish-born sister duo, respectively. Both groups gave incredible performances before Ben Howard -- who was recently featured as Variance's "Ear Candy" selection -- dominated the Honda stage. We were honestly surprised to see such an enormous crowd absolutely enthralled with the British singer-songwriter, who recently stopped by Jimmy Kimmel Live to perform his latest single "Only Love." Grammy-winner Esperanza Spalding followed with that sultry voice. Fans watched as she passionately charmed the audience with soulful lyrics and an incredible talent for maintaining vocals and playing bass simultaneously. It's unreal (see video).

WATCH: fun. Debuts 'Carry On' Music Video

fun. continues to "Carry On" in their latest music video, this time for the third single off their breakout album Some Nights. The video -- and the song, for that matter -- provide a fitting way to head into the final stretch of what has been a very good year for the trio.

WATCH: The Black Keys' 'Baddest Man Alive' Video feat. RZA

Following the recent release of The Man With The Iron Fists soundtrack, The Black Keys and RZA have released new visuals for their featured track "The Baddest Man Alive." It is the first of several clips due to release in support of the RZA-produced film, which stars Russell Crowe, Cung Le, Lucy Liu and RZA, among others. It is "presented by" Quentin Tarantino.

WATCH: Bruno Mars Scores Big As 'SNL' Host, Debuts New Song

Bruno Mars set himself apart from many of his popstar peers, joining a small group of performers that have served simultaneously as host and musical guest on Saturday Night Live. Admitting during this week's opening monologue that he had no acting or comedy experience, the 27-year-old musician went on to prove such a disclaimer unnecessary, giving a solid performance from start to finish.

WATCH: Imogen Heap Debuts New Single, Music Video

Grammy winning songstress Imogen Heap is back this week with a new single and a video to go along with it. The English composer debuted "You Know Where To Find Me" during a Google+ Hangout, performing it live before showcasing the video and taking questions from fans. The beautiful new single, which is now available for purchase, is off her upcoming album, tentatively titled the Heapsongs Project.
