Leftism is the first studio album by electronica musicians Paul Daley and Neil Barnes under the name Leftfield. The album was released in 1995 on Columbia Records. Leftism consisted mostly of reworked versions of previous singles by Leftfield and new original pieces. The album contains guest spots from musicians not associated with dance music at the time such as John Lydon from Public Image Ltd. (and formerly of Sex Pistols) and Toni Halliday from Curve. The album was described as progressive house, although some journalists found that label too limiting, suggesting the album incorporated many genres. After completing the album, the duo in Leftfield initially were not happy with it.
On its release, the album was well received from the British press with positive reviews from the NME and Q. The album was nominated for the Mercury Prize in 1995 but lost to Portishead. Leftism sold well and was released months later in the United States. Critics have praised the album as one of the major album-length works of dance music, with Q referring to it as "the first truly complete album experience to be created by house musicians and the first quintessentially British one".
