The cream of Ireland’s independent rock and dance artists have joined together for the charity album “Collaborations: The Best of the Irish Independent Music Scene.” Profits raised from the set, released by Crimson Entertainment, will benefit the Chernobyl Children’s Project, an Irish-based charity which has links to U2 frontman Bono’s wife, Ali Hewson, and whose executive director, Adi Roche, was a candidate in Ireland’s last presidential election.
