What were the household objects
Following the success of Dark Side of the Moon, the Floyd were in something of a quandary as to what to do next. One idea they had was to try to create an entire album using only sounds produced by common household objects. The Floyd used a number of recording sessions in the latter months of 1973 to experiment with such unconventional instruments as wine bottles, aerosol spray cans, rubber bands, tape, and others.
The Pink Floyd encyclopedia lists 1-4, 8-10 and 22-31 October; 12-14,19-21 and 26-28 November; 3-5 December 1973 as the recording dates.
In the end, they managed to get three songs recorded before giving up on the project as “a bit daft.” However, some bits and pieces (the wine glass sounds) were used in the beginning of SOYCD.
