Jem Aswad Senior Music Editor Rina Sawayama is one of a handful of artists who released an album just as the pandemic was beginning and watched, astonished, as their stars rose during lockdown. The Japanese-British singer’s debut, “Sawayama,” was a wild fusion of Lady Gaga with nu-metal guitars, but also showed a penchant for sentimental ballads amid the power chords and intensity. The album won a co-sign from none other than Elton John, and its videos got her cast in the fourth installment of Keanu Reeves’ “John Wick” series, due in March. In fact, Elton was one of many people who spoke out against Sawayama’s exclusion from eligibility for England’s BRIT and Mercury awards because she isn’t a U.K. citizen, even though she’s lived in England since the age of 5. After #SawayamaIsBritish became a trending topic on Twitter, the British Phonographic Industry changed the eligibility rules to include anyone who lived in the country for at least five years, including her.
