Hi,Not sure exactly what you're looking for, but do check with your local Irish pubs for any weekend sessions.
Singers provide the flute and fiddle players with a much-appreciated break to go smoke a couple of cigarettes.
The Irish Echo or Irish Voice should have a list of sessions. A lot of the ones I used to attend (before our baby arrived) have dried up in the Bronx area. I've heard there's a swinging scene in Queens these days.
