For years, Jackson C. Frank was as ghostly a legend as they come. Even the relatively few record collectors who revered his work were only aware of the lone LP released during his lifetime. For all most listeners knew, Frank made an incredible album in 1965 and then vanished, despite that record having been produced by Paul Simon.

1975 Mekeel Sessions features six tracks recorded in the mid-'70s at a studio in Lake Hill, New York about five miles from Woodstock where Frank was living at the time. Only uncovered decades later, these recordings hum with the same mysterious warmth that defined Jackson at his peak. His guitar work, alternating between strummed and fingerpicking, is perfectly understated. His stark and somber voice, more weathered than the lighter tone on his debut.

While the Mekeel tapes were intended for Frank's sophomore album, it never came to be. What one hears is not a singer-songwriter fading out of view, but rather a singular artist who never stopped trying to build his own world – even when no one was watching. For fans of everyone influenced by Jackson: from Nick Drake, Sandy Denny and Bert Jansch to more contemporary acts like Elliott Smith, Vincent Gallo and Iron And Wine who surely used Frank's sparse approach as a template.
