In Richard Berkeley-Steele, ENO has found an exciting new Siegfried, having already lost one by the wayside. Wagner's "untaught" hero, too often mere brawn, is here a force of nature, bullish, attractive and fatally cocky. He can sing impressively as well as act, a rarity in Wagnerian heldentenors. Gidon Saks's Hagen was loud and bloodcurdling, if hardly subtle.
