Passage: After Lourdes's birth, Madonna became involved in Eastern mysticism and Kabbalah, introduced to her by actress Sandra Bernhard. Her seventh studio album, Ray of Light, (1998) reflected this change in her perception and image. She collaborated with electronica producer William Orbit and wanted to create a sound that could blend dance music with pop and British rock. American music critic Ann Powers explained that what Madonna searched for with Orbit "was a kind of a lushness that she wanted for this record. Techno and rave were happening in the 90s and had a lot of different forms. There was very experimental, more hard stuff like Aphex Twin. There was party stuff like Fatboy Slim. That's not what Madonna wanted for this. She wanted something more like a singer-songwriter, really. And William Orbit provided her with that."
