The experimental-minded JACK Quartet begins its two-night residency tonight with a sold out show at the Transformer Station. For tonight's concert, the group will perform Georg Friedrich Hass' String Quartet no. 3 "In iij. Noct." The group will play the piece in complete darkness — musicians will simply play from memory while positioned in different parts of the room. Tomorrow night at 7:30 at the Cleveland Museum of Art's Gartner Auditorium, the group will present the world premiere of two Cenk Urgen compositions. Tickets to that performance are $30 to $45.
