Main Course is the Bee Gees' eleventh album, released in 1975, and their last album to be released by Atlantic Records in the U.S. under its deal with Robert Stigwood. This album marked a change for the Bee Gees as it was their first album to include disco hits. Working with Atlantic producer Arif Mardin, who had also produced their previous album, Mr. Natural, and engineer Karl Richardson at Criteria Studios in Miami, their music became much more R & B influenced. Main Course also featured the debut of Barry Gibb's falsetto. The famous album cover was designed by US artist Drew Struzan.
