WATCH: NEEDTOBREATHE Dresses Up For 'Girl From Tennessee' on 'Conan'

NEEDTOBREATHE performed on Conan Wednesday night, thus marking the band's fifth late night appearance this past year (Leno, Letterman, Ferguson, Kimmel and now Conan). Since it was Halloween (and fittingly the night before the CMAs), the guys decided to dress the part in their performance of "Girl From Tennessee," donning hair and makeup to impersonate Dolly Parton, Taylor Swift, Reba McEntire, Tina Turner and Minnie Pearl.

WATCH: The Avett Brothers Perform Tribute to Brooklyn on 'Jimmy Kimmel'

Jimmy Kimmel had planned to host his show this entire week from Brooklyn, but superstorm Sandy had other plans, forcing the late night host to adapt. His musical guest Thursday night were The Avett Brothers, whose album The Carpenter recently released. Although the band had been scheduled to promote their latest release, Kimmel explained that he asked them to perform a song of their 2010 LP, "I and Love and You."

How's this to start your November? The boys of Vampire Weekend appeared on Jimmy Kimmel Live for the halloween episode. Complete with makeup to celebrate, the band introduced a previously-untitled track now called "Unbelievers." The song appears to be a nod to the Monkees' "I'm A Believer." They also performed "Oxford Comma" off their debut self-titled album from 2008.

WATCH: Austin City Limits Festival 2012 Highlights [Day 3]

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:

SUNDAY (Day Three)
The final day of ACL kicked of with British indie rockers ∆ (Alt-J) unleashing an energetic set. Our recent FutureSounds pick, they are rising quickly in the U.S., with "Tessellate" being one of their frontrunning tracks. Next, Kimbra performed (her solo set) and drove the enormous crowd wild with her undeniable stage presence. No, seriously, she commands the stage. If we were handing out awards, the flamboyant 22-year-old would get the one for best stage presence. Dressed in a pink pon-pon-like top and similar oversized grass-green skirt, she made certain all eyes were on her from start to finish, delivering a breathtaking performance.

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).
