Coordinates: The IBC Recording Studios (in which IBC stands for International Broadcasting Company) were recording studios located at 35 Portland Place, London, England. In the 1960s and 1970s the studios become internationally famous after being used by some of the biggest recording artists in the world.
Chas Chandler bought the studios in the late 1970s and renamed them Portland Recording Studios. The address was also home to George Peckham's cutting rooms (Porky Prime Cuts) and Radiotracks Studios, a company specialising in recording and producing radio commercials. It was later bought by Don Arden and was run by his son David Arden.
In their long history, and especially in its heyday as IBC, the studios manufactured much of their own equipment under the direction of Denis King. The quadraphonic mixing desk designed in the early 1970s was still in use in the late 1980s by Radiotracks, though in a different building. The desk had been built to take advantage of the quadraphonic technology that had been pioneered for music, though this never became popular and the desk was never used for that purpose in its music days. 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. Although all the large mixing desks have been dismantled, one smaller desk, a nine-into-three desk used for locations recording, still exists and is in private hands. The small, fully transistorised desk, built around 1958, was used to record "My Old Man's a Dustman" by Lonnie Donegan in 1960.
The sound samples for the pioneering Mellotron keyboard were recorded at IBC in the early 1960s.
Notable artists who have recorded at IBC Studios include:
The studios are today occupied by Musion das Hologram Ltd, which uses the space to demonstrate its life-size hologram technology, and to record footage for broadcast as holographic images. Madonna used the system to appear as her virtual self at the Grammy Awards.
