Hot on the heels of an exhibition of Denmark's Skagen school of painters at the National Gallery of Ireland, some traffic in the other direction. Next week sees the opening of two substantial shows by Irish artists in Denmark. One, at the Holtegaard Gallery close to Copenhagen is devoted to the late paintings of Jack B. Yeats. The other, at the Nordjyllands Museum in Aalborg, features Tony O'Malley's work from the 1950s and `60s . . . If you want to see the Chilean lyric tenor Tito Beltran in action next week, you'll have to go to Limerick: the Bord Gais New Year Opera Gala concerts at the City Hall, Cork on Saturday and at the National Concert Hall, Dublin next Saturday (January 23rd) are sold out, but there are still tickets to be had for the University Concert Hall, Limerick on Wednesday next, January 20th . . . Over 30 Irish jazz musicians travel to a 45eme Parallele, a festival of music and drama in Valence, France, running from Wednesday, January 27th until Saturday 31st . . .
