Richard Wagner's 15-hour Ring Cycle will be broadcast in its entirety on one day over Easter on BBC Radio 3.
Wagner's Ring is currently being staged in Paris
The performance, conducted by Daniel Barenboim in Bayreuth, Germany in the early 1990s, will be broadcast on 17 April, a bank holiday.
The day-long event, part of Radio 3's 60th birthday celebrations, will include just four 15-minute breaks.
The station will also be celebrating St George's Day on 23 April with a day devoted to English music.
The Ring Cycle features Anne Evans as Brünnhilde, Siegfried Jerusalem as Siegfried and John Tomlinson as Wotan.
Presenter Donald Macleod will guide listeners through the day from 0800 BST, with synopses and beginners' guides available online.
The station's spring schedule also features an adaptation of Alan Bennett's The History Boys starring Richard Griffiths and a new production of Chekhov's Swan Song starring Paul Scofield, both broadcast on 12 March.
The centenary of Samuel Beckett is also celebrated in April with new productions of his plays Krapp's Last Tape and Embers.
