The Incredible String Band was one of the most complex groups to have ever existed, primarily due to the versatile ability of two of its original members to master multiple instruments and their almost extrasensory sensitivity, which allowed them to create a wide variety of styles, all within the framework of folk. The roots of this formidable band lay with the duo Robin Williams and Clive Palmer, both multi-instrumentalists who began their career in the Edinburgh area in the early 1960s. A few years later, they recruited guitarist and vocalist Mike Heron and vocalist Licorice McKenzie, as well as various occasional members who would prove to be quite prolific and talented musicians. In 1966, after securing a contract with the Elektra label, they recorded their first album, "Incredible String Band", which was highly acclaimed by critics at the time. This debut album showcased strong vocal lins and well-crafted instrumentation of music with medieval and traditional folk influences, although still quite rudimentary. After a second, more experimental album with strong influences from Eastern and Hindu spirituality and hints of acid folk, titled "5000 Spirit Or The Layers Of The Onion" (1967), they released their most ambitious work, "The Hangman's Beautiful Daughter". introducing psychedelic elements and avant-garde touches. The expansive "A Very Cellular Song" is the best example of the album's progressive side, featuring a wide variety of acoustic and exotic instruments, subtly layered with a Hammond organ, creating a varied and warm soundscape with Eastern influences and a certain dark undertone. From this point on, the band would record a dozen more albums and embark on numerous tours around the world, solidifying their reputation as an iconic band of early avant-garde folk, until they finally disbanded in 1974 to pursue individual careers within the genre of intimate and progressive folk.
