While I'm sewing kilts on Saturday mornings, I like to listen to Celtic music on WFUV 9am-12noon:

From 12-1pm they broadcast Thistle and Shamrock with Fiona Ritchie

Other times I like to listen to Pandora Radio. My brother, Bruce Greene, is on, playing old time fiddle music.
I love Alyth McCormack, Karan Casey, Kate Rusby, Loreena McKennitt....
I love the Scottish band, Scocha....They've come to NYC several times for Tartan Week...
I like William Jackson and Sue Richards...
Other favorites are Ian and Sylvia, Simon and Garfunkle, the Beatles..
.
My favorite instrumentals are violin, cello, lute, harp...
I like Vivaldi, Mozart, Bach...
Baroque music, opera arias and Early music.
But most of all, Celtic music!
