In January 2019, when Weezer performed live at Rock In Rio Brazil, they were riding the wave of their self-titled album, commonly referred to as "The Black Album," which was released just a few weeks later on March 1, 2019. This performance showcased the band's evolution and enduring popularity, as they transitioned from their earlier sound to a more contemporary and diverse style, reflective of their willingness to experiment with different genres. Notably, their previous album, "Pacific Daydream," released in 2017, had already demonstrated a shift in tone and approach, which continued to develop in the subsequent release. The Rock In Rio show also emphasized Weezer’s status as festival favorites, featuring hit songs from their extensive discography, and highlighting their ability to engage a large and energetic audience.
