Her success lies largely with her ability to work and write within traditional modes. Many of these songs sound as though they have been around over the centuries. - Ira Mayer, New York Times

On Almost Commerically Viable, both Peggy and Irene's voices are really fresh, despite their combined ages of over a century. Peggy sounds clear and sharp in the hard-hitting song 'Guilty' and seductive in the jazzy 'Sweet Heroine'. Irene has a soft voice, high and light, which complements Peggy's voice well.
