The long awaited digial (CD) copy of this classic children's album is now out! The album was released to very positive critical reviews and is a best seller. Combined with the charming color drawings of artist Peggy Lipschutz, it ranges over themes both profound and silly -- from the 'sounds' of silence, to ways to explore the world and science, to the sounds of a squeaky sneaker and a reminder not to forget to breathe! 'I work out to this every day,' said M. Sargent, professor at Parkland College in Champaign, Illinois. And she's no child. Others have remarked that this is the 'only children's album the adults enjoy as much as the kids.'
