Abigail Washburn is an American clawhammer banjo player and singer. She released Abigail Washburn The Sparrow Quartet in couple of years ago while living in china. Inspired by a volunteer experience for Sichuan Quake Relief in China, Abigail joined forces with Shanghai Restoration Project’s David Liang in March 2009 to create Afterquake. The benefit EP (a portion of each sale benefits Sichuan Quake Relief) was released on May 12, 2009, the one-year anniversary of the 2008 Sichuan Earthquake. Over the course of two weeks, Washburn & Liang recorded and produced the entire project, which features electronic mixes of student voices and sounds from the disaster zone, in Sichuan, China.
