Stereophonic
In 1976, a famous British-American rock band composed of drummer Simon, married couple bassist Reg and keyboardist/vocalist Holly, and longtime partners guitarist/vocalist Peter and vocalist/tambourinist Diana are in the early stages of recording their next album in a recording studio in Sausalito, California. They are assisted by two sound engineers, Grover and Charlie. Despite the significant - and scarcely precedented - studio support, the members' individual conflicts coupled with mounting tensions among the group, and eventually the engineers, causes the recording process to take around a year.
