In a way this album has been over 40 years in the making. Duncan Mackay was playing in a club he started in Johannesburg called the Branch Office, the first venue in South Africa where you could go and hear Prog Rock. Georg Voros (although underage at the time) would go and listen to Duncan. 40 years on Georg approached Duncan to play on and mix a solo album. The Bletchley Park Project grew from this prior collaboration.
