It's an all-Bach program this week on Classical Music Amarillo. Margaret Lacy opens the show with "Sleepers, Wake," recorded in St. Andrews on the legendary Aeolian-Skinner Opus 1024 organ. We'll also hear Bach's "Suite for Unaccompanied Cello, No. 1 in G major," performed by Jeffrey Lastrapes. Plus, the Amarillo Virtuosi play the "Brandenberg Concerto, No. 3" with conductor Michael Palmer.
