In late 2004, Banks formed a new improvising band, Harmony in Diversity, with Andrew Booker and Nick Cottam (who had been working together as duo Pulse Engine). They played a short UK tour in March 2006, and released an album called "Trying". Booker left the band soon after. He was replaced by David Speight [http://www.davidspeight.weebly.com] and the band continued to play further dates in the UK and Hungary in 2007. Banks was also planning a related project with keyboardist Gonzalo Carrera.
