Barb Reeves is a veteran Boulder's Dinner Theatre performer with a number of strong characterizations to her credit. But in this BDT production of Slow Dance With a Hot Pickup, a gentle-hearted musical about a group of people competing to win a truck, she put something into her portrait of a harried waitress that we've never seen from her before. Her Marie was strong-minded but completely unsentimental. Reeves displayed a singing voice that could rock the house, but also a low-key sincerity that stayed with you long after the lights went out.
