Whether realistic or abstract, three high-summer art openings brought large sizes and vivid colors to Vineyard gallery walls. Rez Williams debuted new landscapes from a trip to Maine to the A Gallery on State Road. Carol Brown Goldberg is showing abstract paintings at The Vineyard Playhouse lobby that feature numerous experimental painting techniques to create vibrant, ecstatic compositions. And the Granary Gallery featured three artists: Jean Staples, Heidi Lang-Perrinello and David Wallis.
