The Polite Force by Egg

Released in 1971, The Polite Force is the second album by British band Egg. It is often regarded as the band’s best work and displays an advance in compositional maturity which moves away from the lingering psychedelic-pop sensibilities of their debut album toward a more avant-garde instrumental approach. The music is a fine example of early English progressive rock, bearing many similarities to Soft Machine. Although the music of Egg does have occasional singing, it is mostly instrumental and as such relies on tight ensemble playing and interesting thematic and melodic material with extended chordal harmonies and irregular time signatures.
