The mastermind behind Nuova Idea was composer Gian Piero Reverberi, who was also the producer of Le Orme and wrote most of the tracks on these albums under the nickname Ninety The Underground Set were often thought to be an English group, their first album having been issued in many European countries. It's interesting to notice that the group has been mentioned as English in Vernon Joynson's Tapestry of Delight book. But in an interview with Paolo Siani on the Italian Musikbox magazine, the drummer was one of the first to reveal that the musicians playing on this band's two albums were in fact Nuova Idea, as Radio Records (the label on which the first album and the singles appeared) was distributed by their label Ariston at the time.
