"Study in Time'' (photo collage), by Jamie Cascio, in the group show ''TIME: Brickbottom Artists Association Members' Exhibition,''  July 13-Aug. 19. Its gallery is in Somerville, Mass.

The curator writes:

"Time's Up, Time Out, Time Warp, Timeless - 

"Time presents itself in drama, music, photography, philosophy, science...and life. It's connected to change, growth, mortality and decay. We mark it, track it, keep it, bend it, save it, lose it and waste it. It passes, drags, floats, and flies, but what is time? This summer, the Brickbottom Gallery members' explore this elusive concept.''
