Many of Jon 7's ideas come from things seen in dreams, and "Towers" is a prime example. In the dream this album's concept came from, Jon 7 was walking through an old house where he found a large map indicating the presence of two large towers, towers that didn't actually exist but were indicative of two equipment set-ups that were referred to as the 'blue tower' and the 'red tower'.
The concept as it became applied was one of two groups of people, who have settled a new land, built towers and suddenly felt the need to out-engineer one another, with the sounds representing their respective inventions and developments, which through the sounds can identified as being quite different from each other's.
The dream also indicated the presence of a 'white tower', but you'll have to wait to see how that story develops.
