Martyn Bates and Troum – To a Child dancing in the wind
By definition, ‘ambient music’ cannot be ‘vocal music’ unless only wordless syllables are sung (by my traditional definition, that is). Recognisable text generally asks too much attention, and singing almost always requires chords that can be ‘remembered’ easily. Still – in the last year I have heard some great examples of music that defies this narrow definition. There are quite a few examples of “songs” that work very well with a clearly ambient, droney background. For a good example, listen to Wheely Down cover by the Uncertain Music Corps.
