"Isobel" is a song by Icelandic singer-songwriter Björk for her second studio album, Post (1995). Written by Sjón based on a story by Björk, the lyrics of "Isobel" tell the story of the title character, who is magically born in a forest and sends a message of instinct amongst the logical thinking of the people of the city. The story of Isobel has been explored in "Human Behaviour" and "Bachelorette", forming a trilogy. The track was released as the second single for the album in August 1995 by One Little Indian. Featuring additional songwriting by Nellee Hooper and Marius de Vries, string arrangements by Eumir Deodato and production by Hooper and Björk, "Isobel" combines a lush orchestral sound with electronic breakbeats.
