+## From Jim Peters:
+##
+##	!! EXPERIMENTAL !!
+##
+##	30 minute tape.  Gently goes from the edge of alpha down
+##	through theta to deep delta.  The tape fades out in deep
+##	delta.  This is designed to help someone get to sleep.  The
+##	carrier also drops in pitch to give that `sinking feeling'.
+##
+##	Headphones recommended, low volume.
