From a fellow guitarist's perspective, this album is a masterpiece.  The well-placed silence between mesmerizing, shimmering guitar licks is deafening.  Otis is masterful at telling a story or setting a mood with the confluence of his anguished singing, espressive guitar-playing, and impeccable timing.  What sets him apart from other, perhaps flashier, guitarists, is the patience he shows while telling a story---i.e., the spaces between guitar playing, the patience in holding a note.  His phrasing on the guitar is simply hypnotic.  One of his secrets is that he puts on a silky-smooth vibrato while deftly bending the string---a difficult task for many.
