Japanese soul diva representing the 2010s, "Hanah Spring," has finally completed a self-produced album that has become the culmination of her career after five years since her last release! Based on R&B that overflows with 90s flavor, which she considers to be her roots, the album features sophisticated production work by mabanua, Shingo Sekiguchi, DJ HAZIME, Shun Ishiwaka, Uyama Hiroto, grooveman Spot, and other producers, as well as soulful vocals that resonate with the heartstrings, crossing over into the present tense of neo-soul. The album features a variety of guest musicians, including Ruito Kasahara, Emi Tawada, CHAN-MIKA, and Kzyboost, and also includes a cover of Erykah Badu's superb R&B number "Appletree," which she admires.
