[1] In the 1960s and 1970s, the studios become internationally famous after being used by recording artists such ase Status Quo, the Kinks, the Who, Bee Gees, Cream and others.
Bolstered by the success of clients such as the Who, IBC was regarded as one of the top recording studios in London in the late 1960s.
[2] In July, 1978, IBC was bought by musician Chas Chandler, who renamed them Portland Recording Studios.
Instead the quadraphonic system on the desk was put to good use for mixing soundtracks for large events, including a celebration of 800 years of the Lord Mayors of London at the Guildhall.
Joe Meek, Denis Preston and later Adrian Kerridge left IBC to found Lansdowne Studios in 1958.
