When OperaUpClose's bar-side production of La bohème beat the ENO and Royal Opera House to the Olivier Awards' Best New Production gong earlier this year, it was hard - even in these award-sceptical parts - not to delight in the David versus Goliath-like nature of the victory. State funds and high-profile support has since beefed up this fragile dinghy of a venture. One new fan, Mark Ravenhill, was invited to direct Monteverdi's The Coronation of Poppea. Another, Michael Nyman, was asked to write an intervention aria. Could these artistic stars halt a recent spate of post-bohème production missteps?
