Except for the fact that they are both well-established artists, the two men featured in I Gotcha Covered: Roland Bernier and Bill Vielehr have nothing in common. Roland Bernier's visual language is actually language — in this show, giant letters in alphabetical order — which he uses as found compositions for his conceptual pieces. Bill Vielehr, on the other hand, does welded aluminum in the form of abstract columns. To make them work in the same show at Walker Fine Art, gallery director Bobbi Walker put the Berniers on the walls and the Vielehrs on the floor, creating what could be seen as a solo within a solo, with each artist standing out on his own.
