I saw a presentation where the speaker had a painting and did not know name or auther but saw it in a gallery in california. The center of the picture depicts a white robed figure (I viewed as Jesus like) not on solid ground. To the right there are 3 or 4 figures sitting like a musical quartet on a foundation. The sky is dark and stormy and there are panels cut in the storm cloud letting in light. I would like to know the name and if there are copies of the painting to be purchased. Thank you,
