Reviews of "Birth of the Cool" have enjoyed the favour of the critics at both the Sydney and the Edinburgh Festival and subsequently in Germany, Melbourne and revivals in Sydney.

John Turnbull received reviews that warmed to his vibrant and versatile on stage energy. Backed by three first class jazz musicians, his colourful and many layered vocal texturing of the beat poets and their lives delivers an evening of spoken and musical virtuosity where cool words and hot jazz are often one whole made up of four parts.

Critics have delighted to "Birth of the Cool" as an evening of originally composed beat era jazz that blends so well with the cool words of the beat poets, their homosexual love and their poetic anarchy.
