Cellist Bion Tsang and pianist Anton Nel make their PBS broadcast debut as cello/piano collaborators on Thursday, August 26, at 8 p.m. on KLRU. The half-hour IN CONTEXT special was recorded in February 2010 in KLRU Studio 6A, home of the venerable live music series Austin City Limits. KLRU’s IN CONTEXT art series presents performances from some of Austin’s leading artists and cultural organizations.
