***RECOMMENDED*** For the casual audience member attending an operatic performance, it is usually not necessary to know much about a production's narrative beforehand. That's the job of the librettist. If you have a good librettist, the story unfolds in real-time, it beautifully complements the rhythm of the composer's score and it is easily understood. However, if the source material happens to be Shakespeare or Greek tragedy, perhaps, you may want to do a little bit of research ahead of time. No need to dig out your old Edith Hamilton edition of "Mythology" however, in order to appreciate the season-opener "Medea" at Lyric Opera of Chicago. Just peruse the synopsis in your program before the curtain rises. The first paragraph will grant you vital information that will fill in memory gaps to Medea's backstory while also helping to answer questions that have major significance on what is her motivation for ultimately devising such a sinister plan. 3 SPOTLIGHTS
