ICE brings new Thorvaldsdottir work to Atlas in atmospheric but ephemeral performance

For a couple of years now, the contemporary music series at the Atlas has done a signal service to Washington by presenting a wide range of important cutting-edge ensembles in significant work. But the Atlas has had a hard time helping to establish a context for this work: in showing why people should want to come, and why they should care. Thursday night's concert, the last of the season, was a perfect example of fine music and fine performances adding up to an event that fell a little flat.
