Ummagumma is the fourth studio album by the English progressive rock band Pink Floyd. It is a double album and was released on 25 October 1969 by Harvest Records in the UK and by Capitol Records internationally. The first disc is a live album that contains part of their normal set list of the time, while the second contains solo compositions by each member of the band recorded as their fourth studio album. The artwork was designed by regular Floyd collaborators Hipgnosis and features a number of pictures of the band combined to give a Droste effect.
Although the album was well received at the time of release, and was a top five hit in the UK album charts, it has since been looked upon unfavourably by the band, who have expressed negative opinions about it in interviews. Nevertheless, the album has been reissued on CD several times, along with the rest of their catalogue.
