Michael Berkeley's guest is Pakistan-born writer and filmmaker Tariq Ali, whose books examine the often troubled political relationship between West and East. A passionate music-lover, his choices begin with Billie Holiday singing Strange Fruit and end with a highly topical song by Hans Eisler and Bertold Brecht, taking in along the way music by Gluck, Schubert, Tchaikovsky, Shostakovich and the great Muslim Sufi poet and musician Bulleh Shah.
