It's notoriously difficult for playwrights to get their work produced, particularly if the works are full-length rather than one-act plays. Steven Tangedal and Nicholas Sugar, Theatre Group's executive and artistic directors, are to be applauded for mounting two evening-length plays by Denver writers. Josh Hartwell's Reaching for Comfort and Melissa McCarl's Painted Bread, which featured a powerful performance by actress Karen Slack in the role of Frida Kahlo, both had flaws, but they were also vivid and original. It's only through collaboration with other theater artists that a playwright can develop, and it's this kind of risk-taking that keeps the theater scene alive.
