A heavyweight vinyl edition of Texas blues legend Sam Lightnin' Hopkins' solitary album for the Psychedelic imprint, International Artists. Recorded in January 1968, Free Form Patterns stands out in Hopkins' discography due to the unusual line-up on the sessions, with the veteran bluesman - fuelled by homemade moonshine - supported by a young, hip rhythm section, comprising Danny Thomas and Duke Davis from The 13th Floor Elevators (both high on acid at the time).
