Vadnais and Williams are the undisputed standouts of the group...Calliope may get the joke about chewing the scenery, but it’s truly Williams’s Melpomene that is making a five course meal out of Britton Mauk’s (literally) flashy and graffiti-covered set. Whether she’s perpetrating strange magic or leading her siren daughters in mean-spirited melody, she is deliciously evil and impossible to take your eyes off of.
