Final 'Echoes'performance with Richard Wright (Pink Floyd)

"Echoes" is a song by the rock band Pink Floyd, and the sixth and last track on their 1971 album Meddle. It is 23 and a half minutes long and takes up the entire second side of the original LP. The track evolved from a variety of different musical themes and ideas, including instrumental passages and studio effects, resulting in the side-long piece. The music was written by the group, while Roger Waters' lyrics addressed themes of human communication and empathy, which he returned to in later work.

The song was performed live regularly by Pink Floyd from 1971 to 1975, including a performance in the film Live at Pompeii (1972). It was used for the opening shows on the 1987 A Momentary Lapse of Reason Tour but subsequently dropped. David Gilmour revived "Echoes" for his 2006 On an Island Tour, which featured Richard Wright, but retired the piece after Wright's death in 2008. The studio recording was used in the film Crystal Voyager (1973) while an edited version is included on the greatest-hits album Echoes: The Best of Pink Floyd (2001).

"Echoes" has been regarded by critics as an important song that transitions between Pink Floyd's early experimental material as a cult band, and later mainstream success. Several publications have remarked it as one of the best songs by the group. The group's members have mixed views of the track, but it was a particular favourite of Wright's.
