One hidden gem in the north east of Scotland is the folk-hard rock band Sons o' the Soil. I class them as a hidden gem as they seem to disappear for some time, return and disappear again. It's understandable however, that due to work, it can be hard for them to stay completely commited to the band. It's a shame because they are awesome and even better live. Mixing traditional scottish instruments like the accordion and fiddle in with some good old rock vibes is a recipe of brilliance. Gordy Strathdee has a rough-around-the-edges raw rock voice which is strangely complimented by the harmonies of his daughter, Jo's, sweet and soulful voice.
Two of my friends, Amy Steele and Anthony Spencer are in the band (Amy playing the fiddle and Tony playing the cello) who are incredibly talented musicians, as are the entire band. If you ever get the chance to see them gig...it's well worth it (best chance is usually at the Speyfest music festival). With local friends and fans guaranteed to be in the crowd, it's a great atmosphere and as I said...the music is even better live than on the recordings.
"When The Light Hits The Day" is one of my all time favourite songs.
