The first weekend of the Coachella Valley Music & Arts Festival wound down Sunday night after three long, loud days in the desert. But the annual bash went out with an enourmous bang. Keeping with the previous day’s conveyer belt of guest appearances, day 3 featured unexpected collaborations (Bieber! Blige! Drake!) and standout performances from a few acts with less famous friends as well. Here are the 20 standout moments from Sunday.
3:40 PM: Chance The Rapper's main stage performance gets a superstar cameo when Justin Bieber hops onstage. Wearing a white bucket hat and black tee, the Biebs played "Confident," his Music Mondays entry that featured the Chicago MC.
5:45 PM: Mexican alternative rockers Zoé earn a slew of new, U.S. fans with their impressive sun-soaked main stage set.
4:50 PM: The 1975 ends its set with their hit single "Chocolate," which causes a female audience member with a camera propped on a pole to twirl around and point the lens at herself. Who knew British Rock could induce selfie spins in Indio?
5:18 PM: Superchunk is making the best of its Gobi Tent performance, despite playing to a criminally small number of people. At the adjacent Mojave Tent, meanwhile, Rudimental is performing an overflowing crowd.
5:27 PM Blood Orange's funky set has a famous supporter: Sam Smith is spotted nodding along and chatting with friends in the crowd of the afternoon performance.
6:04 PM Blood Orange decides to experiment a bit for his show's finale, as "Time Will Tell" also includes Dev Hynes singing snippets of Outkast's "Ms. Jackson," Lana Del Rey's "Born To Die," then back to Outkast for "Hey Ya."
6:11 PM: Another nod to Lana Del Rey is heard when Flosstradamus drops a "Video Games" remix in the Mojave Tent.
6:35 PM: No video screens? No problem. Neutral Milk Hotel is one of the rare artists to not allow themselves to be projected onto the jumbo screens flanking the Outdoor Theatre stage, and the screens instead show a steady shot of the Coachella Ferris wheel throughout the haunting set.
7:31 PM: Calvin Harris wastes no time in his main stage takeover, opening with "Feel So Close" and proving the energetic yin to the muted yang of Neutral Milk Hotel's set-closing "Engine."
8:01 PM: The song "I Need Your Love" graces the main stage for the second time of the weekend, with Calvin Harris dropping the Top 10 hit two days after Ellie Goulding did the same on Friday night. Fans betting on a Goulding cameo came up empty, as the U.K. singer was in Los Angeles for the MTV Movie Awards.
8:27 PM: "West Coast" finally arrives, as Lana Del Rey debuts her highly anticipated new single early in her performance.
9:07 PM: Ending her set with "National Anthem," Lana Del Rey strides toward the front row of the crowd, hugging many fans and even kissing a lucky few on the lips.
9:10 PM: Beck isn't exactly a Calvin Harris-like dance guru, but his cover of Donna Summer's "I Feel Love" gets the blood pumping as the night becomes increasingly chillier.
9:57 PM: Disclosure brings out its first vocal guest: Aluna Francis of AlunaGeorge, on hand to sing "White Noise."
10:29 PM: ...And then Disclosure brings out Mary J. Blige to perform their remix to "F For You." Sam Smith also stops by his friends' set to play "Latch."
10:39 PM: The surprise guests keep coming as Donald Glover and Drake shock fans with appearances during Jhene Aiko’s late-night Gobi-tent set. Is there anybody who’s not at Coachella?
10:43 PM: Apparently not. Motörhead, who have already pummeled the crowd with the heaviest riffs heard all weekend, welcome Guns N’ Roses guitar god Slash to the stage for a balls to the walls rendition of “Ace of Spades.” Any marbles Coachella had left are instantly lost.
10:56 PM: Arcade Fire frontman Win Butler decries the rampant "fake VIP room bullshit" at Coachella, saying that festival goers yearning for special passes needn't worry about a VIP area that "super sucks."
11:40 PM: Debbie Harry joins Arcade Fire onstage as a surprise guest, duetting with Regine Chassagne on the Blondie classic "Heart Of Glass" before serving as a backup on "Sprawl II (Mountains Beyond Mountains)."
12:02 AM: Arcade Fire run past the Coachella curfew by marching into the audience and continuing their finale of "Wake Up" sans microphones (Win Butler instead wields a megaphone).
