Berkeley painter Deth P. Sun’s work, taken a whole, can be read almost like a comic book. With each solo show, his blank-eyed cat character — whom longtime fans have come to know well — returns for new adventures. Coming up on April 25, the artist has a solo show at Grumpy Bert in Brooklyn titled “Being and Nothingness.” This time, his mystical feline tackles themes of global proportions. Set against a backdrop of a star-lit sky, Sun places the microcosm of his protagonist’s world in the larger context of the universe. Amid the endearing visuals are bouts of melancholy as our hero ultimately must face his own mortality. “Being and Nothingness” will be on view through May 24.
