CA7RIEL & Paco Amoroso went viral after their performance in NPR's Tiny Desk Concert

CA7RIEL & Paco Amoroso first gained global recognition and fame after their performance on NPR Music's 'El Tiny' Desk Concert, which dropped on October 4, 2024.

Since then, their rise to fame has been meteoric. On April 4, 2025, the hip-hop duo made their debut on The Tonight Show Starring Jimmy Fallon.

Later in April, CA7RIEL & Paco Amoroso performed two consecutive sold-out shows in New York's Bowery Ballroom as part of their world tour - which also contains pit stops in renowned music festivals like Coachella, Glastonbury, Fuji Rock (in Japan), Roskilde (in Denmark), and Lollapalooza (in Berlin and Paris).

Speaking about their South American roots, CA7RIEL told Billboard Español in April:

"Coming all the way from el culo del mundo (the a** of the world), we didn’t expect this. To suddenly appear here, with all these cameras and lights — it’s insane. We’re from way down there; we’re still adjusting to being up here."

The duo also told Billboard about the musical influences in their family, with CA7RIEL growing up with his father playing guitar, and Amoroso listening to Argentine rock icons since childhood.

Then, talking about their knack for experimenting with different genres, CA7RIEL & Paco Amoroso said:

"We go through different phases... At one point, it was all about rapping, then playing instruments, which was how we started. We even had a phase where we just gamed all the time and did nothing else. Then you keep evolving."

The hip-hop duo has worked together as well as individually before reuniting for their 2024 album, BAÑO MARÍA, and a nine-track EP dropped in March 2025, PAPOTA.
