Since before Christmas theartsdesk has been reviewing the past decade and previewing the year to come in the arts. As an extra we offer this special edition of The Seckerson Tapes, in which Edward Seckerson and Igor Toronyi-Lalic discuss the year in music, which, in the concert hall, saw the triumph of the new romantics in conductors Riccardo Chailly and Yannick Nezet-Seguin and, operatically, saw the arrival of three penetrating new productions of operatic classics: the English National Opera's Peter Grimes, Covent Garden's Tristan und Isolde and Glyndebourne's Rusalka.
