ROLW (Ro), whose genre-defying music evokes J-POP, rock, R&B, and hip-hop and whose lyrically inventive, original writing stands out, has built his own universe with the album 'philosophical & imperial,' a 12-track collection unfolding in multiple layers. He will stage his first full-band Billboard Live concert. For this day’s special session guests, longtime ally ”長江 崚行” (1st stage) and ”高本 学” (2nd stage), who co-starred with him in the musical Hetalia series, will grace the stage. Also confirmed is the appearance of KIKUMARU, the rapper and close friend who contributed as a guest on the track 'Career,' for both stages. Don’t miss this highly anticipated performance, a moment when mellow music is born.
