Yes,but not at Covent Garden and not with Keenlyside. I saw it in Frankfurt in January 2010 (and Mefistofele next day). It was performed "in englischer Sprache mit deutschen Ubertiteln". It started very well with the storm but thereafter it was rather bitty, and scandalously did not use Shakespeare's text most of the time (the guilty party was someone called Meredith Oakes but I'm sure that Ads could have demanded Shakespeare if he'd wanted to). The Prospero (Adrian Erd) was also a bit underwhelming. Cyndia Sieden, the stratospheric Ariel, was the only cast-member to have been in the Covent Garden premiere. Probably worth seeing, and I imagine that the Met will provide a good staging.
