 In April 2004 Steve Hamilton was replaced as Earthworks pianist by Gwilym Simcock, an outstanding young musician who was already being widely talked about and who now needed to build the foundations of a career.At around this time, Bruford was losing patience with the economic and bureaucratic nature of a transatlantic music career which constantly created obstacles with visas and musicians union demands.Although he would use his regular musicians when he could (including for studio recording dates), future Earthworks performances in the United States would use local musicians as and where required.
