Paint, canvas, watercolors, paper, multi-media collage – these are all familiar components in making art. Michelle Mackey’s joint compound, however, is a bit of a surprise to the uninitiated. Holly Johnson Gallery, 1845 Levee St., No. 100, hosts Mackey’s second show in the venue, Michelle Mackey: Double Take. The exhibition is one of “new paintings,” and yes, those paintings are created with build-ups of joint compound on wood, sanding and shellacking and vinyl paint. Mackey tackles time and memory with relation to space and setting. The result is ethereal and a bit overwhelming, in the most beautiful way possible. Double Take opens with a reception for the artist from 5-8 p.m. Saturday, May 13, and continues through August 12. Holly Johnson Gallery is open 11 a.m.-5 p.m. Tuesdays-Saturdays and by appointment.
