Cauld Blast Orchestra, Blazin' Fiddles, Old Blind Dogs, Na h-Oganaich, Isobel Ann Martin, Silly Wizard, John and Phil Cunningham, Arthur Cormack, Ceolbeg, Adam McNaughton, The Proclaimers, Red Hot Chilli Pipers, James Graham, Ishbell MacAskill, Anna Murray, Dougie Maclean, Matt McGinn, Deaf Heights Cajun Aces (for anyone who thought the Scots couldn't play Cajun music!), Brian McNeill, Foundry Bar Band, Jock Duncan, Sheena Wellington, Catriona Watt, Arthur Johnstone, Wolfstone, Jim Reid, Saltfishforty, Wrigley Sisters, Gaberlunzie, and the list goes on...
Hope that at least gets you started.
Slainte! And happy travels!
Mike (Auchterless)
p.s.: Any music from the last ten or so CDs from Sgoil Chiuil na Gaidhealtachd. Amazing music from the Gaelic school in Plockton. It's hard to believe that these are high school kids!
