Until last October, Argentinian musical duo Ca7riel & Paco Amoroso were more or less a regional act. Known for their experimental blend of Latin trap, pop, and rap, the pair had a fanbase, but still weren’t cracking more than 3,000 daily streams across services like Spotify, Apple Music, and YouTube. Within a week, they shot up 4,700%—hitting 222,000 daily streams—according to exclusive data firm Luminate, which powers the Billboard charts. Suddenly Ca7riel & Paco Amoroso were global pop stars.  What changed? On Oct. 4, the pair were featured in a Tiny Desk Concert, part of NPR’s 17-year-old video series featuring musicians performing stripped-down sets behind an office desk in the cramped Washington, D.C. headquarters of the public broadcaster.  In the concert video, the artists play five songs from their debut album Baño Maria, which came out last April. Paco’s raspy voice emerges from underneath a puffy blue trapper hat while Ca7riel sports an over-the-top pout and a vest made of stitched-together heart-shaped plush toys. The pair sing entirely in Spanish, backed by their Argentinian bandmates (sporting shirts screenprinted with their visas) and an American horn section. The duo’s performance quickly took off across the internet. Within five days, it had racked up more than 1.5 million views on YouTube, and hit 11 million in little more than a month. It also reverberated across social media: the NPR Music Instagram post garnering nearly 900,000 likes, and TikToks clips garnered hundreds of thousands of views.  In a year that featured Tiny Desk performances from buzzy stars like Chappell Roan and Sabrina Carpenter, as well as established acts like Chaka Khan and Nelly Furtado, Ca7riel & Paco Amoroso’s concert was the most-watched of 2024. It currently sits at 36 million views.  That virality translated to an influx of bookings for the duo, including a performance at Coachella in April, and upcoming slots at Glastonbury in June, FujiRock Japan in July, and Lollapalooza and Outside Lands in August. Ca7riel & Paco Amoroso’s global tour includes sold-out dates at Mexico’s 20,000-capacity Palacio de los Deportes and Chile’s 14,000-seat Movistar Areana—and was previewed by an appearance on The Tonight Show Starring Jimmy Fallon in April.  “Through Tiny Desk, we’ve noticed media approaching us, promoters being very interested in offering their spaces and festivals, and many media outlets opening doors to show us to the world,” says Jonathan Izquierdo, the band’s Spain-based tour manager who began working with the duo shortly after the Tiny Desk Concert debuted. “We’ve managed to sell out summer arena shows in record time and we’re constantly adding new concerts. Promoters are knocking on our doors to get the Tiny Desk effect.” Bobby Carter [Photo: Fenn Paider/courtesy NPR] Tiny Desk, Big Influence The Tiny Desk effect is something Bobby Carter, NPR Tiny Desk host and series producer, has seen firsthand. Carter has been at NPR for 25 years, including the past 11 on the Tiny Desk team. He took the reins when Bob Boilen, the longtime All Songs Considered host who launched Tiny Desk in 2008, retired in 2023.  The series—which now has more than 1,200 videos—began as an internet-first way for Boilen to showcase performances from musicians that were more intimate than what happens in bigger concert venues. The first installment, featuring folk artist Laura Gibson, went up on YouTube. Today, the concerts are posted on the NPR site with a writeup and credits, as well as YouTube, where NPR Music has 11 million followers. NPR Music also clips installments on Instagram, where it has 3 million followers.  In the early days, NPR staff reached out to touring bands to secure bookings. Acts coming through DC could often be cajoled into filming an installment before heading out to their venues for that night’s sound check. Now, musicians come to DC just for the chance to record in NPR’s offices.  “We don’t have to worry about tours anymore,” Carter says. “Labels and artists are willing to come in solely for a Tiny Desk performance. They understand the impact that a really good Tiny Desk concert can have on an artist’s career.” Early on, the stripped-down nature of the Tiny Desk—artists can’t use any audio processing or voice modulation—lent itself to rock, folk, and indie acts. But a 2014 concert with T-Pain, in which the famously autotune-heavy singer unveiled an impressive set of pipes, showed how artists from a broader array of genres could shine behind the Tiny Desk.  “Everyone knows at this point that they’re going to have to do something different in our space,” Carter says. “It’s a bigger ask for hip-hop acts and electronic acts, but most artists now understand how important it can be if they nail it.” Carter highlights rapper Doechii as an artist who overhauled her sound for her Tiny Desk concert in December.
