Zhang Hao, Ricky, Kim Kyu-bin, Han Yu-jin, and Yoo Seung-eon reunited as AND2BLE and released their debut album ‘Sequence 01: Curiosity’. The five-song, approximately 14-minute album presents the sensibilities of third-generation K-pop in a modern way. The title song ‘Curious’ emphasizes the members’ vocal crossover based on synth pop and future house. Members, including Zhang Hao and Ricky, participated in writing lyrics and expressed new beginnings and their own identity throughout the album.
