In the mid-1960s, Horn’s life changed profoundly after his travels to India and meeting Maharishi Mahesh Yogi (spiritual teacher of The Beatles). He became a practitioner of Transcendental Meditation, which redirected his music toward spiritual introspection and acoustical exploration.
1968: Inside the Taj Mahal was recorded spontaneously within the Taj Mahal’s echoing dome.
His flute improvisations reverberating through the architecture created haunting, meditative overtones. This album is widely regarded as one of the first true New Age recordings. It pioneered the use of natural reverberation as a compositional element.
Horn continued the Inside concept, recording within sacred and resonant spaces around the world. Inside the Great Pyramid (1976), Inside the Cathedral (1983), and Inside the Taj Mahal II(1989). Each project used natural acoustics to enhance meditative improvisation—transforming architectural space into an instrument. His music during this era emphasized peace, reflection, and spiritual unity, aligning perfectly with emerging New Age ideals.
Horn moved to Vancouver, Canada, continuing to record and perform globally. He collaborated with musicians across genres, such as jazz, Indian classical, and world music. Albums like Traveler (1990), and China (1997), blended global influences with serene tone color. Horn became an influential figure for ambient, world, and New Age artists such as Deuter, Steven Halpern, Kitarō, and Andreas Vollenweider.
