Hidden treasures reveal themselves tonight when Lost & Found Video Club presents Videons: An Evening With Steve Beck. Beck — a veteran of forward-thinking spectacles who created light shows for Jimi Hendrix and worked in the experimental '70s film scene of Northern California — exemplified his life's work with the development of his direct video synthesizer system known as Videons. Blending music, performance art and poetry, the resultant marriage of soul and vision — a true synthesis — became a phenomenon he calls "illuminated music." Tonight he appears to expound upon the Videons, screening everything from early VR breakthroughs to breakdancing animation devised on an Apple II.
