What about "An Ataireachd Ard" (The High Surge, but usually known in English as The Eternal Surge of the Sea)and "Cearcall a' Chuain" (The Ocean's Cycle), both of which can be heard on Catherine-Ann McPhee's CD "Canan nan Gaidheal"? Also Eilean M'Araich (Island of my Upbringing) and Laoigh an Iasgair (The Fisherman's Hymn) sung by Mairi McInnes.
