Acoustic Guitar on Vinyl

Michael Newman on Sheffield if you can find it.  Some say the best acoustic guitar sound ever recorded.  Elliot Fisk plays Scarlotti on Mark Levinson Recordings.  Not really acoustic, but Michael Hedges, Ariel Boundaries on Wyndam Hill, Gittarr Kvartetten on Opus 3 and Berkley Guitar on Tomkins Square records.  All great recordings AND great music.  All too rare, unfortunately. 

 As mentioned-Michael Hedges, and Alex De Grassi who also adds the "New Age" vibe to the music.  Muriel Anderson,Earl Klugh 

Going a little deeper check out Charlie Byrd, Paco De Lucia.

You may already be familiar with Tommy Emmanuel? Gabriel y Rodrigo? Both current popular performers.

Guy Van Duser - Stride Guitar

For pure audiophile delight try Sir John a Lot. by John Renbourn

Excellent production and performance.

Norman Blake, "Whiskey Before Breakfast", on Rounder Records
