KT's fourth studio album overall, Invisible Empire/Crescent Moon, is her first to be released on Blue Note. KT describes the album as full of songs from the heart, adding I followed my path of truth and ended up in a different place. IECM is made up from two sessions with a season in between them, and KT saw the work as naturally separated into two distinct parts - an 'A' side and a 'B' side. The first batch sees songs like the exquisite Made Of Glass and Yellow Flower focusing on the themes of mortality, a subject close to her heart following the passing away of her father last year. The second batch evokes an ethereal mood, more reflective of deeply felt changes in outlook and shifts in her personal life. Together they add up to KT's most cohesive and affecting album to date.
