I am a big fan of musical theater, both in film and on stage, and have attended many shows throughout the years where music is interwoven into the story.
“2 Pianos 4 Hands” at the Colony Theatre in Burbank requires a different sensibility, and your own enjoyment of this play may very well be determined by your knowledge of and appreciation for classical music.
It opens with the two characters, Richard (Roy Abramsohn) and Ted (Jeffrey Rockwell), playing a concerto by Bach that continues for a while, leaving one to wonder when dialogue will commence that allows you to know the two people onstage. This is an indicator of what will follow, as it seems there is more music than dialogue, and that may or may not be a problem — depending on what you are seeking.
