Siobhan Miller, “Mercury” (Songprint Recordings)-The eagerly anticipated follow up to Siobhan Miller’s critically acclaimed 2017 set,”Strata,” dispenses with the impeccable cover versions which have been such a feature of her recorded output to date in favour of a batch of freshly minted songs,several of them penned in close collaboration with her former Salt House bandmate Euan Burton, who also handled the bass and production duties on “Mercury.” Scottish singer-songwriter Siobhan’s sublime fusion of contemporary and folk influences could charm the proverbial birds down from the trees, and she’s in particularly fine fettle here on stand-out tracks such as “The Western Edge,” “Losing” and “Mercury” itself.
