BBC Radio 3 began a two-week residency on the South Bank on Monday when it opened a temporary studio in the foyer of the Royal Festival Hall.
Until the end of March the station will broadcast most of its programmes live from the Riverside Terrace Cafe at the Royal Festival Hall giving listeners unprecedented behind-the-scenes access to the station during Southbank Centre's Pull Out All The Stops festival.
The organ festival – which continues until June – marks the completion of the restoration of the organ in the Royal Festival Hall.
"We are delighted to work with BBC Radio 3 in this partnership, helping us fulfil Southbank Centre's passionate belief that art should be available to all," said Jude Kelly, artistic director of Southbank Centre.
"The full restoration of the Royal Festival Hall organ is a historic moment and this collaboration means that audiences across the UK can be part of what we do at Southbank Centre."
