Thursday and Sunday's shows are about silence.

I found music and artists--from all styles and genres--who express silence in and inbetween the notes.

This week's music ranges from classical (Isao Tomita plays the music of Debussy) to Chick Corea's jazz group Return To Forever, and French electronic duo Air (left).

Not to be missed is the downtempo, space arrangement of Sarah McLachlan's "Silence," and surprise guest appearances from Johann Sebastian Bach and Aaron Copland.
