On a sweltering afternoon in the thick of August, the artist Kenny Rivero, 41, opens the door to his Bronx studio. A drum set and some guitars are kept in one corner of the room. Exercise rings dangle from the ceiling. Lego sets share shelf space with a library of art monographs, religious texts and science-fiction novels. His show at Charles Moffett gallery in Manhattan, “Steward: The Ballad of a Super Super,” is opening soon, and his studio is packed with work, though his personal effects also crowd the walls, given the same pride of place as his paintings in progress. There’s the door from his childhood apartment, his old TV from middle school, the curtains from the first place he lived on his own and a raft of fixtures reclaimed from the building where he once worked.
