Despite its title, Musique pour 3 Femmes Enceintes doesn't contain music for pregnant women as much as it does music about pregnant women.
It was conceived (as it were) when Montreal-based producer Marc Leclair's wife and several of her friends were all pregnant at the same time.
Over the course of ten tracks, each labeled according to a point in the pregnancy ("64th Day," "205th Day," etc.), Leclair attempts to convey the moods and flavors of the experience.
The music is mostly soothing and warm, but at various points it's marked by subtle moments of tension and excitement (note the quiet but fairly frenetic beats on "33rd Day" and the dark synth tones that pull against the relaxing sounds of flowing water on "85th Day").
Fans of Brian Eno's pioneering '70s experiments in ambient music will recognize the general flavor here, though there's more complexity to much of this music than initially meets the ear.
The notes provide no indication of whether Leclair's wife feels he succeeded at creating a faithful musical rendering of the experience of pregnancy, but what really matters is whether he succeeded at creating interesting and enjoyable music, and that he has.
