Titling her play Heartbreak Hotel is a major bit of misdirection from New Zealand dramatist Karin McCracken. Elvis’s recording of his classic 1956 single (by Mae Boren Axton and Tommy Durden) is barely mentioned, and its bouncy blues are a far cry from McCracken’s gloomier deep dive into the nature of heartbreak. Directed by Eleanor Bishop, the play reaches beyond McCracken’s personal drama to examine unexpected, more clinical aspects of a breakup, such as psychological, biological, and physiological symptoms. Interspersed with those sequences are musical interludes—she took up the synthesizer to occupy herself after the end of a six-year relationship, and she has learned six “powerful” chords.
