HARMONICA is not the first instrument that springs to mind when Scottish traditional music is mentioned, but Donald Black has been an assiduous as well as persuasive advocate. This disc focuses exclusively on what he describes as "slow airs and reflections" from the Highland and Gaelic traditions (a slightly livelier waltz quadrille from Canada is the exception), played on the distinctively tuned Scottish Celtic harmonica he has developed with Hohner. It could have been a recipe for a rather bland collection in other hands, but Black's technical facility and expressive interpretations ensure it remains an engaging listen, and he throws in a vocal version of the Gaelic song Gleann Bhaile Chaoil for good measure. Other innovations include a first-ever pibroch on harmonica. A stellar cast of helpers includes Aly Bain, Phil Cunningham, Duncan Chisholm and Allan Henderson, who also produces.
