CRAVITY has unveiled a highlight medley for its ninth mini album 'sonorous', to be released on the 30th. On the 26th, agency Starship Entertainment released a video on its official social media channels featuring snippets of seven tracks, including the title song 'LOUDER'. The video presents tracks across a range of genres, from intense hip-hop-based songs to electronic and dance pop, with mysterious, dreamlike visuals. Title track 'LOUDER' combines the members' delicate vocals with lyrics such as 'following repeated breaths' and 'this moment that kicked my heart', and is marked by a dramatic shift from a gentle melody and an addictive chorus. Wonjin, Allen, Serim, Hyeongjun and Taeyoung took part in writing the title track's lyrics. The album also includes Serim's self-composed 'LOVE ME', Woobin's 'Fantasy' and Taeyoung's 'Odd One Out'. 'sonorous' carries the message that different sounds come together to create one great resonance, and will be released on major online music sites at 6 p.m. on the 30th. CRAVITY, a nine-member group (Serim, Allen, Jungmo, Woobin, Wonjin, Minhee, Hyeongjun, Taeyoung and Seongmin) that debuted on April 14, 2020, held the fan concert 'BT FESTA' at Olympic Hall in Seoul's Olympic Park this February.
