After announcing her co-headlining spot at the Super Bowl Halftime Show in 2020, singer and songwriter Shakira is back in the studio and recording new songs. Last week, she remixed Camilo and Pedro Capó’s pop-reggaeton hit, “Tutu.” Then, on Friday night, she shared a video of herself singing a vastly different song: Green Day’s 1994 pop-punk anthem, “Basket Case.” With her producer on acoustic guitar, Shakira sang the first verse and chorus before busting out her own air guitar moves. She posted the minute-long video on both Twitter and Instagram. Green Day bassist Mike Dirnt responded, “Bacáno!” Might this hint the return of the rockera Shakira we knew and loved in the 1990s? Or even a Green Day collaboration? It’s hard to say. But in a Tuesday interview with DJ and producer Zane Lowe for Apple Music’s Beats 1, the Colombian superstar disclosed that she has been working on new material of her own. “Yesterday I finished a song and I was so thrilled,” Shakira said. “So we’ll see. I just want to put music out there.” Shakira is also raring to release a concert film in film theatres this fall. Chronicling her 2018 El Dorado world tour – in support of her Grammy-winning album of the same name – ‘Shakira in Concert: El Dorado World Tour’ will premiere internationally on November 13, 2019 in more than 2,000 theatres across 60 countries. Tickets are now available on the film’s website.
