Mr. Burstein unleashes his rich baritone with roof-raising force when Tevye's emotion is at its height, bringing home the character's indomitable will, often hidden beneath his self-deprecating humor and sorely tried by his rebellious daughters. Mr. Burstein's way with a classic Jewish joke is assured but unforced, his performance affecting but not overscaled, in keeping with the production's emphasis on the musical's emotional underpinnings, rather than the frosting of shticky comedy.
