The E.A.R. Unit, one of the boldest and most idiosyncratic contemporary chamber ensembles working today, turns its refined attentions to composers named Linda. The group is premiering Wanderer by the brilliant Canadian composer Linda Catlin Smith, commissioned by the Unit; the sensuous multimedia work Forecast by fellow Canadian Linda Bouchard; and the haunting Moonsick by Dublin-based Linda Buckley. The egalitarian program does extend fearlessly into non-Linda territory: After Forgetting, a sizzling new work by Keeril Makan, who was also commissioned by the Unit, and Daniel Salecich’s mesmerizing Generator (urban speed time-out).
