At turns funny and yet emotionally moving, MOTHERS AND SONS portrays an older widow (“Katherine,” played by Joan End) who pays an unexpected visit to the New York apartment of her late son’s partner (“Cal,” played by Mark Neufang ), who is now married to another man (“Will,” played by Nathan Marinan).  This very special concert reading is an enriched artistic experience, through a much more expansive rehearsal period typically enjoyed in a standard stage reading.  Also, a significant majority of the script will be memorized by the artists, unlike a true, mere “reading.”  And some physical movement (”blocking“) will be incorporated into the performance.  The necessary stage directions will be narrated by actress Pamela Stace and this dynamic concert reading is directed by Mark Bucher.
