Probably the main Irish Music contact in Boston is Larry Reynolds, President of the local branch of the Comhaltas Ceoltóirí Eireann. He is a fiddler and knows everybody and everything that's happening and would know about Irish music and language events. His number is 781/899-0911.
The Boston branch website is:http://www.comhaltasboston.org, or Click Here
