This week I chat to Australian singer-songwriter Gretta Ray about Blake Mills' 2010 album 'Break Mirrors'. Mills may be better known as a producer (Alabama Shakes, Dawes) but today we explore his own music. We talk about how Mills wrote this album as a calling card for his session work, his poetic but unpretentious turns of phrase, his unique but completely tasteful guitar work, Mills' production on Laura Marling's latest album and the advantages of operating slightly under the radar.
