Coming up on Saturday is the first appearance in 2009 by the Mayo melodeon player Alan Morrisroe, a welcome visitor to the Irish American Association of North Jersey (www. iaanj.org) and its house concert and session maven, Iris Nevins.  It is the official release of a new CD, Old Irish Melodeon Masterpieces, recorded live at last year’s appearances, and that includes many tunes preserved from his granny Catty Neill, but also some of his wonderful stories accompanying the tunes in an Oiche Cheoil fashion around the fireside in the homey Clubhouse of the IAANJ. For good measure he is bringing along another Mayoman, Paddy Joe Tighe, who is also a box player and ballad singer with a store of songs he collected.   Action gets underway at 7:30 p.m. on March 7 in Rockaway, New Jersey with a free concert followed by a session afterwards.  The pair will also appear at the Monday night Landmark Tavern session on March 9 and Dempsey’s Pub on March 10, both of which are in Manhattan.  For more info contact Iris Nevins at 908-813-8617 or irisnevins@verizon.net On Saturday, March 14 at Town Hall at 8 p.m., Natalie McMasters, the premier Cape Breton fiddler leads her band into Manhattan for a display of talent that has rocketed her to international fame.  On Sunday, March 15, some Boston talent is visiting the Big Apple for a concert at eclectic Jalopy Folk Center (www. jalopy.biz) in the gritty Red Hook section of Brooklyn. There is a double bill featuring Annaliva (Flynn Cohen, Liz Simmons, Brendan Carey Block, Emerald Rae and Stuart Kenney) for Celtic and Appalachian music and songs and the husband and wife duo of Matt and Shannon Heaton whose appearances are rare in New York City.
