HuffPost Arts' Haiku Reviews are biweekly features where we invite critics to review exhibitions and performances in short form. Some will be in the traditional Haiku form of 5x7x5 syllables, others might be a sonnet or even a string of words. This week Peter Frank and Laurence Vittes give quick takes on visual arts, theatre and classical music from 'invisible artwork' to the Los Angeles avant garde. Is there a show or performance that you think people should know about? Write a Haiku with a link and shine a light on something you think is noteworthy. We'd love to hear about it!
