Seein as this is becomming a general arena for whistle players - I thought I ought to mention that few of the Irish Trad recordings I have heard over the years exhibit what is best about the instrument. The style of playing - mostly competitive - is alien to a long tradition in Ireland of a simple but rhythmic pattern. The Fleadh IMHO has almost destroyed that. If interested in this topic you could do well to check out the Clare 'school' and you'd be in select company too - Capt O'Niell of the 1000 and 1 tunes - and nearly all the modern autorities on the subject.
Where you may hear some of that old style is on Micko Russell's recordings.
