From the infectious trance beat of Sumatra's Folk Dangdut music, featuring the rabab (violin) or saluang (flute), to the highly refined and glorious Orkes Gambus (orchestral Arabic music with 'gambus' literally meaning 'oud'), said to have been brought to the island by Islamic settlers from Yemen, the 17 tracks featured here will instantly convince the listener of the expressive beauty and diversity that Sumatra has contributed to the world music theater.
