In the late ‘60s and early ‘70s, the inherent weirdness of folk met switched-on psychedelic rock and gave birth to new, strange forms of acoustic-based avant-garde music. Artists on both sides of the Atlantic, including The Incredible String Band, Vashti Bunyan, Pearls Before Swine and Comus, combined sweet melancholy and modal melody with shape-shifting experimentation to create sounds of unsettling oddness categorized as acid or psych folk. In the mid-2000s, a new generation of artists collectively tagged New Weird America and spearheaded by Devendra Banhart, Espers, and Joanna Newsom rediscovered and renewed acid and psych folk Seasons They Change tells the story of the birth, death, and resurrection of this genre. It explores the careers of the original wave of artists and their contemporary equivalents, finding connections between the generations and uncovering a previously hidden narrative of musical adventure.
