Coachella '14 Sunday: The Cameos Keep Coming, From Blondie to Bieber

 Call it "Cameochella." At this point, the special guests at Southern California's Coachella Music & Arts Festival generate more buzz than any of the actual official headliners. After Saturday featured surprise appearances by Beyoncé, Jay Z, Gwen Stefani, Snoop Dogg, and many others, the cameos kept coming on Sunday. Really, only at Coachella would Justin Bieber and Slash ever grace stages on the same field on the same day.

Justin, fresh off his impromptu club appearance at last month's South By Southwest festival, was the first big surprise of Sunday, joining rising Chicago MC Chance the Rapper (aka Chancellor Bennett) on the Main Stage for a run-through of their Music Mondays collaboration "Confident." According to People, Justin's on-again, off-again love interest Selena Gomez watched from the stage wings as Justin sang lines like "She got a body like that/I ain't never seen nothing like that," and "Then she started dancing, sexual romancing/Nasty but she fancy, lipstick on my satin sheets."

The Biebs looked the part of an old-school rapper in his bucket hat, baggy pants, gold chain, and multiple bandanas; however, while stunned spectators whipped out their cell phones to document this bizarre Coachella moment, it's still unclear just how welcome he was at the fest, what Selena thought of the performance, or what effect his cameo had on Chance's street cred.

On the opposite end of the cameo spectrum was Guns N' Roses guitar god Slash, who joined fellow metal legends Motörhead for an eardrum-rupturing rendition of "Ace of Spades" and a mega-jam finale. The roaring riffs of Slash and Motörhead axeman Phil "Wizzö" Campbell could be heard all the way across Coachella's vast polo field, practically bleeding over into Arcade Fire's Main Stage revue.

Meanwhile, literally yards away from Motörhead's Mojave Tent gig, Childish Gambino (the hip-hop alter ego of "Community" actor Donald Glover) and Drake joined up-and-coming soul songstress Jhene Aiko in the Gobi Tent to perform "Bed Peace" and "From Time," respectively. Not to be outdone, English house music duo Disclosure doubled the cameo fun during their epic Outdoor Theatre show, bringing on Mary J. Blige for their collabo "F for You" and recent "Saturday Night Live" sensation Sam Smith for "Latch."

But the cameo to end all Sunday cameos took place during above-mentioned Main Stage headliners Arcade Fire's set, when rock goddess Debbie Harry joined the Canadian collective to perform the Blondie classic "Heart of Glass." Arcade Fire's Régine Chassagne graciously, worshipfully led Debbie up the stage's stairwell and to the microphone, then provided backup vocals while her husband and Arcade Fire's frontman, Win Butler, played piano. This segued into Arcade Fire's own "Sprawl II (Mountains Beyond Mountains)," with Régine on lead vocals and Debbie accompanying. "Debbie f---ing Harry!" Win declared at the end of it all, as the thrilled audience cheered and Régine and Debbie adorably embraced.

Later in Arcade Fire's set, Win gave a "shoutout to all the bands still playing instruments at this festival" — a barbed comment about Coachella's ever-increasing EDM focus. The weekend's many guitar-based, older artists — like the Replacements, Dismemberment Plan, and Afghan Whigs — had played to disappointingly tiny crowds, while the Sahara and Yuma dance tents had been consistently packed. In fact, when one of Sunday's bigger electronic artists, Calvin Harris, spun the Killers' "When You Were Young" and the crowd enthusiastically erupted, the irony was not lost — since if the actual Killers had appeared at Coachella this year, they probably would have performed for a far-from-capacity audience.

However, Sunday's lineup thankfully featured some guitar-brandishing acts, besides Motörhead, who proved that rock is not dead at Coachella — or in general. For instance, British punk veterans the Toy Dolls pulled a respectable crowd to the Mojave Tent (opposite the very different Calvin Harris's set) and kept a proper counter-clockwise, Doc-Martens-kicking-up-dust slam pit going at full churn throughout their high-energy performance. "Do you think I'm getting too old for this?" spiky-haired frontman Michael "Olga" Algar asked the crowd. It was likely a rhetorical question, but fans ceased their slam-dancing just long enough to shout back, "Noooooo!"

Also rocking, in their own way, were much younger Manchester new-wavers the 1975, who should consider changing their name to the 1985. Basically, imagine if a John Hughes movie had been filmed at Coachella — that's what these blokes sounded like. With a glossy, jangly aesthetic reminiscent of Scritti Politti, Go West, and the Blow Monkeys, the quartet played a frothy, poppy, feelgood show that was totally retro and yet somehow very of-the-moment — and most definitely guitar-oriented.

And so, that's a wrap… until next week, that is, since Coachella is now a double-weekend affair. Will Coachella weekend two boast different cameos, different setlists, different surprises? Check back for our reports staring Friday, April 18.
