[1] The band was founded in 1969 by twin brothers Colin and Stewart Goldring, who were joined by drummer Nigel Pegrum from Spice and Peter "Mars" Cowling on bass.
In May 1972, the British music magazine NME reported that Gnidrolog was to appear at the Great Western Express Lincoln Festival on 26 May that year, along with Budgie, Skin Alley, Tea & Symphony, John Martyn, and Warhorse.
[2] In 1972, Gnidrolog released both their first and second albums, In Spite of Harry's Toe-Nail and Lady Lake, before disbanding due to a lack of commercial success.
Despite having played gigs with acts such as David Bowie, Colosseum, King Crimson, Gentle Giant, Wishbone Ash, Soft Machine, and Magma in their brief career, they have always remained relatively obscure.
After disbanding, Nigel Pegrum joined Steeleye Span, while the Goldring brothers formed the punk rock band the Pork Dukes in 1976, and later went on to do session work, as did other members.
