"Siobhan Miller was brought up in the Scottish folk scene, and is one of those rare charismatic singers that can hold large audiences spellbound just singing traditional songs unaccompanied. More recently she's been spreading her wings covering contemporary songs and using more in the way of accompanying musicians. "Mercury" marks another step along the road, with a crossover album of entirely her own songs (some co-written with huband, bass player and producer Euan Burton, others with Kris Drever and Louis Abbott) ... With a significant overlap of musicians from Eddi Reader's [new] album and some backing vocals from Eddi herself, the arrangements are fuller and more mellow than on her earlier albums, suiting the contemporary material. That, plus her wonderful voice, means "Mercury" should appeal to a wider audience, without alienating her many existing fans".
