But as anyone who's heard Wainwright interpret Piaf (or noticed a bit of a punk-rock edge to her folk performances) knows, it was probably never Wainwright's intention to be stylistically pinned down. Goodnight City lets Wainwright's jazz side show; it lets her bluesy contemplative side show; it weaves in some French, some soulful retro-pop, and it tries on experimental heaviness and blows off some steam.
