The Episode 139 "Sacred Acoustics", about "brainwave entrainment audio meditation" was very interesting.

After having listened to the podcast, I tried the free sample and it worked better for me than the usual binaural beats used/made by the Monroe Institute or Tom Campbell.

"Sacred Acoustics" added different technologies to the traditional "Binaural Beats": "The convergence of four technologies, monaural and binaural beats, holographic sound and cymatics produces Neural-Helix, a very powerful brainwave entrainment delivery system."[]

The free sample seduced me enought to make me think about ordering a "complete" track.
