Michael Davidson plays vibes and teams with bassist Dan Fortin on this collection of 14 sublime and classy duets. Davidson’s compositions mix rich melodies for a series of “Berlin” tunes, with some effects on “VII” and chimes on “V.” A dash of synthesizer brings texture to the impressionistic “Out of Love” and the team is a bit percussive for “Spiegeln” with the duo going soft and intimate for “Into a Fog” and hitting a spacious atmosphere for “Doorway.” Luminous.
