All the songs on this album were written and sung by Dougie MacLean. While there is his usual guitar accompaniment, he has for this recording enlisted the eleven-piece Perthshire ensemble as his backing band. The strings (violin, viola, cello and double bass) add depth and texture to the arrangements and it works very well. Having said that, the song "Caledonia" is such a great piece of work it sounds great with or without the extras!
