One exercise involved each member playing on a separate track, with no reference to what the other members were doing. Lacking a central theme for the project, the band used several experimental methods in an attempt to spur the creative process. Engineers John Leckie and Peter Bown recorded the main EMI and AIR sessions, while for minor work at Morgan, Rob Black and Roger Quested handled the engineering duties.

They transferred their best efforts, including the opening of what became ' Echoes', to 16-track tape at smaller studios in London (namely AIR, and Morgan in West Hampstead) and resumed work with the advantage of more flexible recording equipment. At the time, EMI was equipped only with eight-track multitrack recording facilities, which the band found insufficient for the increasing technical demands of their project. Returning from a series of tours across America and England in support of Atom Heart Mother, at the start of 1971 Pink Floyd commenced work on new material at EMI Studios (now Abbey Road Studios) in London. The album was well received by critics upon its release, and was commercially successful in the United Kingdom, but lacklustre publicity on the part of the band's American label Capitol Records led to poor sales there upon initial release. The cover has been explained by its creator Storm Thorgerson to be an ear underwater as with several previous albums designed by Hipgnosis, though, Thorgerson was unhappy with the final result. One single, ' One of These Days' b/w ' Fearless', was released from the album. Although the band's later albums would be unified by a central theme with lyrics written entirely by Roger Waters, Meddle was a group effort with lyrics primarily by Waters, and is considered a transitional album between the Syd Barrett-influenced group of the late 1960s and the Waters-led era. With no material to work with and no clear idea of the album's direction, the band devised a series of novel experiments which eventually inspired the album's signature track ' Echoes'.

The album was produced between the band's touring commitments, from January to August 1971 at a series of locations around London, including EMI Studios (now Abbey Road Studios) and Morgan Studios. Meddle is the sixth studio album by English rock band Pink Floyd, released by Harvest Records.
