Risa Oribe, a.k.a. LiSA (meaning Love is Same All), is a bona fide Japanese star who started as an indie vocalist before rising to fame singing songs for the anime series Angel Beats! in 2010. Her style, featuring powerful, upbeat riffs, driving drums and poppy choruses, hints at influences from artists like Avril Lavigne and Rihanna, but her versatile vocals—shifting from soft to explosive just as easily as adopting a darker, goth vibe—are all her own. It's not hard to see how she inspires real devotion with her catchy, hyper-ecstatic anthems topped with her dreamy voice.
