Limited green colored vinyl. 'I feel there are two immediate, recognizable pillars of my style,' Tunstall says, 'I have this troubadour, acoustic guitar-driven emotional side. Then there's definitely a rocker side of me with sharper teeth'. In the last few years, the Grammy-nominated Scottish Musician has expanded on these musical selves by focusing on a trilogy of records, where each album zeroes in on a single concept: soul, body and mind. The first, 2016's 'Kin', was the soul record; 2018's 'Wax' was the body record, and 'Nut' is the mind record. Produced by Martin Terefe, who co-wrote her 2005 global hit 'Other Side of the World,' 'Nut' draws on Tunstall's love of percussive West African grooves as a metaphor for the learning patterns of the mind and is an eclectic album that seamlessly weaves together disparate styles. She found her writing mojo thanks to 'Canyons', a song propelled by a grimy, heavy rock riff. In keeping with 'Nut's theme, the song's lyrics are about the canyon-like physiology of the brain, and explore the parallels between humans developing unique identities and the way nature evolves and is shaped over time. Elsewhere, the lyrics and sound delve into KT's own personal evolution, and the way we all evolve through the repetition of behaviors and our reactions to life experiences.
