ETHER NETRobert Cherry: voice, guitarDavid Mooser: BassBrent Gemmill: DrumsKen Leonard: KeyboardsSome bruises come after a short, sharp blow. Others creep up on you, the result of continuous pressure, applied so slowly that you never even feel the pain-you only see the mark on the skin and wonder what happened. On its third album,"More Strange Bruises," Ether Net inflicts bruises both ways: sometimes with impact, sometimes by building atmospheres that creep up on you. It's an approach the group has perfected since vocalist-guitarist Robert Cherry and bassist David Mooser first began collaborating in 1993. In 2001, drummer Brent Gemmill joined the band, and Ken Leonard, Ether Net's longtime strings and keys arranger, took a more central role in the proceedings. Together, they form an unyielding musical coalition that spans as much musical space as its members span geography. Cherry and keyboardist Leonard are the Americans in the band, both born in New York state, and currently residing in Clevela
