Peggy Seeger: She must be one of the most complete artists around today. -  Belfast Telegraph

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.
