She released her second solo album Strata in February 2018 and supported it with a European tour. Following on from her well received 2014 debut Flight of Time, Strata, consists of eleven songs, from various sources, that Miller grew up listening to and performing in her youth. All newly arranged and recorded by her for the first time, the material reflected on her musical upbringing whilst forging a unique path forward, with her vocal performances atop the collective talents of some of Scotland’s finest musicians including Kris Drever and Aidan O'Rourke of Lau and Admiral Fallow frontman Louis Abbott.
Winner of 2018 BBC Folk Award for ‘Best Traditional Track’, at which she was also nominated for 'Best Singer', Miller is the only ever three-time winner of Scots Singer of the Year (2017, 2013, 2011). She has made numerous TV and Radio appearances including a cameo in popular drama series ‘Outlander’.
