Obsession and redemption, the twin themes of Wagner's ghostly earliest masterpiece, are two words that could just as pertinently be applied to Jonathan Kent's new production for English National Opera. Obsession is how many non-diehard Wagner opera-goers will view Kent's decision to stage this opera as a continuous pieceit' of drama with no interval. Sure, Wagner originally considered a single-act work, but he quickly dropped the idea. He never conducted or endorsed a staging without a break.

Is it my imagination, or are we getting more Wagner in concert than we used to? It could be a welcome development. How marvellous not to have to tremble at the thought of the latest flight of directorial fantasy: Isolde pregnant, Siegfried as an airline pilot, the Grail temple transformed into the Reichstag (no prizes for guessing which of these is a real case). Instead you can enjoy what Stravinsky called “the great art of Wagner from the direct source of that greatness and not through the medium of pygmies swarming around the stage”.

Popular operatic love stories by Puccini, Wagner and Mozart dominate the regional scene in 2012, but key talents like producer Tim Albery in Leeds, Lothar Koenigs in Cardiff and David McVicar in Glasgow all promise significant stage experiences.

A young chap from Elsewhere woos an alderman's daughter: not Dick Whittington in panto London, but Wagner's Walther von Stolzing in an unseasonal Nuremberg. No one is going to mind the solstitial disjunction - celebrating midsummer revels in the dead of winter - when this great saga of art and society is buoyed up by Antonio Pappano's lovingly prepared conducting, a good cast, lusty chorus and colourful costumes.

Whether or not we believe Wagner’s retrospective rebranding of the opera as a prototype music-drama, “a complete, unbroken web”, Der Fliegende Holländer reliably makes for a vivid evening’s entertainment. Which makes it all the more strange that this is only the work’s third outing at the Royal Opera in almost 20 years.

A legend on the operatic stage, Sir John Tomlinson (CBE) has sung with all the major British opera companies, made countless recordings, and for sixteen years was a fixture at Bayreuth, where he performed leading roles in each of Wagner's epic works. Throughout his career he has worked regularly with English National Opera and with The Royal Opera, Covent Garden, where in 2008 he created the title role in Harrison Birtwistle's The Minotaur.

Next week Sir John Tomlinson (b 1946), renowned mega-bass and routine frequenter of the Covent Garden stage, appears in concert at the Windsor Festival. It is a picturesque halt on a career that sees him circling the world's greatest opera houses in the most epic roles in opera. As is typical of this far from typical singer, the concert is huge in its range, encompassing Mozart, Verdi and Wagner, its lyrical portrayals ranging from servants to gods, from priests to cobblers, human conditions of every shade from ruthless to kind.

Stately females sailed the corridors like grand multicoloured liners. Grown men in boaters and Union Jack waistcoats raced balloons to the Royal Albert Hall ceiling. Beachballs. Streamers. Flags. Fancy dress. One St George's Cross read "Votes for Women!" My first thoughts were: how lovely, in a way, that the mentally ill are allowed a day out like this.

It may have taken her until 2005 to get her Wigmore Hall debut, until 2006 to break onto the stage of the Royal Opera House, but at 53 Susan Bullock has finally arrived, claiming the crown of soloist for this year’s Last Night of the Proms, a firm foothold at Covent Garden and her rightful place as Britain’s finest dramatic soprano. For a singer who “started singing by mistake”, whose musical training began in a council house in Cheshire on a piano rescued from the local rubbish dump, it’s no small achievement.
