Thursday's performance of Next to Normal didn't appear as well-attended as the rest of the Clinton Area Showboat Theatre's opening nights this summer. Yet while this musical trip through a family's struggle with the mother's mental issues may not be as familiar as a Cats or Steel Magnolias, this isn't a piece to miss. The songs by Tom Kitt and book by Brian Yorkey are powerful testimonies to the reality of mental illness for those who suffer from it, and those who suffer through it alongside a loved one.
