ONE HEART is the fourth in Synchronicity's "Collaborations" series of sonic meditations, this time enlisting the help of Native American flutist Marina Raye. The resonant, soulful sounds of Marinašs flutes open the heart to healing and are wonderful for helping one achieve a peaceful state. Here, its haunting strains artfully blend with the synthesized therapeutic atmospheres of Jim Oliver, bringing the listener deep into a state of inner focus and relaxed meditation. The album is divided into two pieces - "One Heart" and "Compassionate Heart," both of which utilize Sir Charles Cannon's Holodynamic Vibrational Entrainment technology. The music features brainwave frequencies in the theta range (3-7.5 Hz), designed for mid-range meditation and cultivating creativity.
