Hikaru Arata released his degital solo single「Hikata」in August and 「Okaerinouta feat.Ann Sally」in October 2020. In these singles, he is not only playing the drums but singing with his sweet and fresh voice not too dissimilar to Daniel Ceaser or Frank Ocean. And his dreamy but strong sound is supported by amazing musicians such as Kazuki Arai from King Gnu(Cb.),Sho Ogawa(Gt.) Jun Miyakawa(Syn.) and Kohei Ando(Gt, Sax).  Furthermore, mastering process of these two songs are produced by Greg Calbi known as legend of engineer had worked on the mastering of John Lennon and Bruce springsteen before. Both of the works are high quality and very gorgeous.
