The reliably challenging and adventurous Unsound Festival kicks off tonight with a pair of ear-clearing experimentalists. Australian guitarist-composer Oren Ambarchi and members of Sinfonietta Cracovia will tie you in _Knots_ when they perform the Sunn 0))) collaborator’s industrial-strength work. Barcelona-based Roc Jiménez de Cisneros and Stephen Sharp, AKA EVOL, have adapted Hanne Darboven’s 36-poem _Opus 17a_ for electronics. The Unsound Festival runs through April 6 at various venues.
