( CNN ) -- `` Are y'all alive ? '' Andre 3000 probed the first-day Coachella goers as he took the stage with Big Boi in the first of their reunion shows . The duo , who have n't performed together since their 2006 Idlewild album , hooked the crowd as they opened with their Stankonia hit `` B.O.B . '' ( `` Bombs Over Baghdad '' ) , before going into a rapid-fire of `` Gasoline Dreams , '' `` ATLiens , '' `` Skew It on the Bar-B '' and `` Rosa Parks . '' Andre 3000 then told the crowd it feels so good to be back , as he talked about the 20-year anniversary of Outkast ( they formed when they were in high school in 1992 and released their debut album in 1994 ) . A notable legend was there to witness the first of their many reunion shows . Andre told the crowd that `` one of his idols '' -- the Purple One , Prince -- was backstage watching as they also ran through `` SpottieOttieDopaliscious , '' `` Roses '' and `` Elevators . '' In the middle of the set , Big Boi and Andre both took time to showcase some of their solo work from their double album , `` Speakerboxxx/The Love Below , '' before rapper Future and Janelle Monae also made appearances . `` This is my favorite group in the entire world , '' proclaimed Monae . `` And what we 're witnessing tonight is history . '' Outkast 's run of mainstream hits came at the end of their set as they went from `` Ms. Jackson '' to `` So Fresh , So Clean , '' `` The Way You Move '' and `` Hey Ya ! '' They then tried to squeeze in an encore song with Killer Mike , but were n't able to perform it before the festival 's 1 a.m. cutoff . Earlier in the day , Grouplove , Ellie Goulding , Chromeo and Girl Talk were among the acts that prepped the main stage before Outkast . Grouplove got the crowd dancing to tracks off their latest album `` Spreading Rumours , '' before Ellie Goulding really got fans fired up with her sunset set , drawing celebrities including Selena Gomez , Kendall and Kylie Jenner and Joe Jonas to the front for the Brit 's high-energy performance . The Top-40 mainstay powered through her list of electro-pop hits like `` Lights '' and `` I Need Your Love , '' before getting everyone to their feet with closer `` Burn . '' Chromeo got the masses moving with their disco-flavored electro-funk . Although they are Coachella vets , this weekend brought them a few festival firsts -- playing on a Friday and performing on the main stage , which they told CNN they found to be more challenging to connect with the crowd . `` On the big stage , they 're 50 feet away , so I could barely hear them , '' said guitarist and lead singer Dave 1 after their set . The duo ran through a mixture of familiar hits , including `` Fancy Footwork '' and `` Momma 's Boy , '' as well as tracks from their forthcoming album , `` White Women . '' Toro Y Moi made a guest appearance for recent single , `` Come Alive . '' Other Day 1 crowd-pleasers included Aloe Blacc , Bastille ( who garnered a crowd that waited through their entire set to hear the familiar hit song `` Pompeii '' ) , Broken Bells and HAIM . The sister act performed on the Outdoor Theatre during the peak of the heat in the afternoon . In between her now-notable `` bassface '' expressions , Este Haim told the crowd that she has been coming to Coachella since 2004 , but that this is the first year she has n't had to run through a rose bush or hop a fence to get inside . Meanwhile in the Sahara tent , newcomer Martin Garrix attracted a crowd that extended past the tent walls as he opened his set with his notable track `` Animals . '' His mix included samples from other Coachella weekend acts like Kid Cudi and Krewella , which had the crowd yelling along to the lyrics . But the most impressive part of the 17-year-old 's hour-set was the striking laser-light show that prompted the majority of the tent to take out their cell phones and capture it on video . Mainstream DJ/producer Zedd continued the fist-pumping/sing-along combination next as he played his radio hits like `` Stay the Night '' and `` Clarity . '' The 24-year-old 's set got the stamp of approval from Oscar winner Jared Leto who Instagrammed a photo from the stage writing `` My friend @ Zedd destroying # coachella . '' With two more days ahead in Indio , California , Chromeo 's Dave 1 summed up the festival 's continued attraction calling it `` the most indie-centric music curation '' with mainstream appeal . `` It 's the festival where you have the coolest bands that get the biggest looks , '' he said . `` Coachella 's got a sexiness to it that no other festival in the world has .
