Denis Gaston is the master of many faces - usually the same face, but changed from unending variables in expression. The body and backdrops also change. All seem to ask that existential question: Who am I? Gaston's paintings are on view at Clearwater City Hall, 112 S Osceola Ave., as part of the city's public art program. The exhibition continues through August; hours are 9 a.m. to 5 p.m. weekdays.
