Oh, I forgot to add, that for anybody wanting to learn some fine tunes, both traditional and composed by Aidan, he does not play them at blinding, breakneck speed like a lot of other virtuosi. Instead, they are played at a speed which can allow you to pick out each note, and learn the melody fairly easily. But he does throw in some nice triplets and ornamentation for the slightly more advanced player. Great stuff!.Seamus
