Though Broadsword has not, as of this writing, had its official world premiere, it certainly appeared to be a finished piece of work when it spooked audiences at the Light Box. The farcical concept — basically "old metal band reunites to rescue its savant lead guitar player, who has written a guitar riff so darkly perfect it opened a portal to Hell" — didn't for a moment obscure the play's big heart or serious subject matter. This was a play about temptation, loyalty, and friendship, given a fantastically atmospheric production by a ceaselessly inventive theater working at the top of its game. Moving and fun.
